Description

Voice-data-radio frequency integrated circuit

Background

The present invention relates to wireless communication systems, and more particularly to transceiver integrated circuits operating within wireless communication systems.

Technical Field

The communication system supports wireless and wired communication between a variety of wireless and/or wired communication devices. Such communication systems include national and/or international cellular telephone systems, the internet, and indoor point-to-point wireless networks. Each communication system is constructed and operable in accordance with one or more communication standards. For example, a wireless communication system may conform to, but is not limited to, one or more of the following standards and/or their various versions, IEEE 802.11, bluetooth, Advanced Mobile Phone Service (AMPS), digital AMPS, global system for mobile communications (GSM), Code Division Multiple Access (CDMA), Local Multipoint Distribution System (LMDS), Multipoint and Multichannel Distribution System (MMDS), Radio Frequency Identification (RFID), enhanced data rates for GSM evolution (EDGE), General Packet Radio Service (GPRS), and/or variations thereof.

Depending on the type of wireless communication system, wireless communication devices, such as mobile phones, walkie talkies, Personal Digital Assistants (PDAs), Personal Computers (PCs), portable computers, home entertainment appliances, RFID readers, RFID tags, etc., may communicate directly or indirectly with other wireless communication devices. For direct communication (i.e., point-to-point communication), a device engaged in wireless communication tunes and communicates through one or more of the same channels (e.g., one of a plurality of radio frequency carriers in a wireless communication system or a particular RF frequency for some systems) with its receiver and transmitter. For indirect wireless communication, each wireless communication device may communicate directly with an associated base station (e.g., for cellular services) and/or an associated access point (e.g., for indoor and in-building wireless networks) over a designated channel. To complete the connection between the wireless communication devices, the associated base stations and/or associated access points may communicate directly with one another via the system controller, the public switched telephone network, via the internet, and/or other wide area networks.

In a wireless communication system, each wireless communication device participating in the communication includes a built-in wireless transceiver (i.e., receiver and transmitter) or is connected to an associated wireless transceiver (e.g., an indoor base station and/or an indoor wireless communication network, an RF modem, etc.). As is known to those skilled in the art, the receiver is connected to an antenna and includes a low noise amplifier, one or more intermediate frequency stages, a filtering stage and a data recovery stage. The low noise amplifier receives an inbound RF signal through an antenna and then amplifies the signal. The one or more intermediate frequency stages mix the amplified RF signals with one or more local oscillations to convert the amplified RF signals to baseband signals or Intermediate Frequency (IF) signals. The filtering stage filters the baseband signal or the IF signal to attenuate unwanted out-of-band signals to produce a filtered signal. The data recovery stage may recover the original data from the filtered signal in accordance with a particular wireless communication standard.

As is also known to those skilled in the art, the transmitter includes a data modulation stage, one or more intermediate frequency stages, and a power amplifier. The data modulation stage may convert the raw data to a baseband signal according to a particular wireless communication standard. The one or more intermediate frequency stages mix the baseband signals with one or more local oscillations to produce RF signals. The power amplifier amplifies the RF signal prior to transmission through an antenna.

As mentioned above a transmitter typically comprises a data modulation stage, one or more IF stages and a power amplifier, and the implementation of these components is dependent on the data modulation scheme in the standard supported by the transceiver. For example, if the baseband modulation scheme is Gaussian Minimum Shift Keying (GMSK), the data modulation stage may convert the digital word (digital words) into quadrature modulation symbols having a constant amplitude and a variable phase. The IF stage includes a Phase Locked Loop (PLL) that generates an oscillating signal at a desired RF frequency that is modulated based on a variable phase generated by the data modulation stage. The phase modulated RF signal is then amplified by a power amplifier according to a set transmit power level to produce a phase modulated RF signal.

As another example, if the data modulation scheme is 8-PSK (phase shift keying), the data modulation stage may convert digital words (digital words) into symbols of variable amplitude and variable phase. The IF stage includes a Phase Locked Loop (PLL) that generates an oscillating signal at a desired RF frequency that is modulated based on a variable phase generated by the data modulation stage. The phase modulated RF signal is then amplified by a power amplifier according to a variable amplitude to produce a phase and amplitude modulated RF signal.

With the ever-expanding demand for wireless devices that support multiple standards, recent trends include the need to integrate more functions on a single chip. However, such a need is not fulfilled in the prior art to implement baseband and RF for multiple wireless communication standards on the same chip.

Accordingly, there is a need for an integrated circuit package that can integrate baseband and RF of multiple wireless communication standards on the same IC chip.

In this embodiment, the functions of the DSP 266, the interface module 234, the data RF section 236, and the voice RF section 238 are the same as previously described with reference to FIG. 14. The function of the data input interface 182 may provide outbound data 250 for display as previously described. The audio codec 180 functions as previously described to provide the outbound voice signal 252 to the voice baseband processing module 230 and to receive the inbound voice signal 264 from the voice baseband processing module 230.

Figure 16 is a schematic diagram of another embodiment of a voice data RF IC70 that includes a data RF section 236, a voice RF section 238, an interface module 234, a voice baseband processing module 230, a data baseband processing module 232, an AHB bus matrix 94, a microprocessor core 190, a memory interface 90, and one or more of a plurality of interface modules. The plurality of memory interfaces include a Mobile Industry Processor Interface (MIPI) interface 192, a Universal Serial Bus (USB) interface 194, a secure digital input/output (SDIO) interface 132, an I2S interface 196, a universal asynchronous receiver-transmitter (UART) interface 198, a Serial Peripheral Interface (SPI) interface 200, a Power Management (PM) interface 124, a Universal Subscriber Identity Module (USIM) interface 120, a camera interface 156, a Pulse Code (PCM) interface 202, a video codec 204, a second display interface 126, a coprocessor interface 136, a WLAN interface 140, a bluetooth interface 146, an FM interface 150, a GPS interface 152, a video camera interface 160, and a TV interface 164.

Fig. 17 is a schematic diagram of one embodiment of the voice RF section 238, which includes a receiver section 270 and a transmitter section 272. The receiver portion is used to convert the inbound RF voice signal 258 into an inbound voice symbol stream 260.

The transmitter portion 272 includes a conversion module 274, a modulation parameter module 276, a first up-conversion module 278, a second up-conversion module 280, a combining module 282, and a power amplifier circuit 284. The power amplifier circuit 284 may include one or more amplifier drivers connected in series and/or parallel, and/or one or more amplifiers connected in series and/or parallel.

In operation, the conversion module 274 and the modulation parameter module 276 receive the outbound voice symbol stream 254, where each symbol may be represented by a mixed coordinate having an in-phase component and a quadrature component. The conversion module 274 converts the in-phase and quadrature components of the symbol into normalized I and Q symbols 286 and 288. This can be achieved by setting the amplitude of the in-phase component and the quadrature component to the same value. For example, the in-phase component is A_Isin(ω_d(t)) and the orthogonal component is A_Qcos(ω_d(t)), wherein A_IAnd A_QThe amplitude of the in-phase and quadrature components, respectively. By setting the amplitude A_IAnd A_QAre the same value (e.g. 1 or A)₀) Then normalized I symbol 286 is sin (ω)_d(t)) and the normalized Q symbol 288 is cos (ω)_d(t))。

The modulation parameter module 276 generates offset (offset) information 290 and transmission property (property) information 292 from the outbound voice symbol stream 254. In one embodiment, the offset information 290 corresponds to the phase information (e.g., φ (t)) of a symbol, which may be calculated by calculating tan-1 (A)_Q/A_I) Thus obtaining the product. Alternatively, the offset information 290 corresponds to frequency information of the symbol.

The modulation parameter module 276 generates the transmission attribute information 292 as a power level setting or amplitude modulation information. For example, if the data modulation method uses phase modulation (e.g., QPSK, GMSK) or frequency modulation (e.g., frequency shift keying) without amplitude modulation, the transmission attribute information 292 will correspond to the power level setting. For an alternative embodiment in which modulation parameter module 276 generates a power level setting, the power level setting may also be generated by voice baseband processing module 230.

If the data modulation method employed includes both phase modulation and amplitude modulation (e.g., 8-PSK, QAM) or both frequency modulation and amplitude modulation, then modulation parameter module 276 generates amplitude information. In one embodiment, the amplitude information (e.g., A (t)) is (A)_Q ²+A_I ²) The square root of (a).

The first up-conversion module 278 combines the normalized I symbol 286 and the offset information 290 to produce an offset normalized I symbol 286 (e.g., sin (ω) sin_d(t) + φ (t))). This signal is mixed with an in-phase local oscillator signal having a frequency corresponding to a second frequency band (e.g., 1920-_RF(t)-ω_d(t)-φ(t))-1/2cos(ω_RF(t)+ω_d(t) + φ (t))). The second up-conversion module 280 combines the normalized Q symbol 288 and the offset information 290 to produce an offset normalized Q symbol 286 (e.g., cos (ω) from the offset information_d(t) + φ (t))). This signal is mixed with a quadrature local oscillator signal having a frequency corresponding to the second frequency band and filtered to produce a second upconverted signal 298 (e.g., 1/2cos (ω) and_RF(t)-ω_d(t)-φ(t))+1/2cos(ω_RF(t)+ω_d(t) + φ (t))). The combining module 282 combines the first and second upconverted signals 296 and 298 to generate an RF signal 300 (e.g., cos (ω) to_RF(t)+ω_d(t)+φ(t)))。

The power amplifier circuit 284 amplifies the RF signal 300 in accordance with the transmission attribute information 292. In one embodiment, the transmission attribute information 292 is a power level setting (e.g., A)_p) Thus, the outbound RF voice signal 256 may be represented as A_p*cos(ω_RF(t+ω_d(t) + φ (t)). In another embodiment, the emission attribute information 292 is amplitude information (e.g., A (t)), and thus the outbound RF speech signal 256 may be represented as A (t) cos (ω)_RF(t)+ω_d(t)+φ(t))。

Fig. 18 is a schematic diagram of one embodiment of the data RF section 236, which includes a receiver section 310 and a transmitter section 312. The receiver portion 310 may convert the inbound RF data signal 246 into an inbound data symbol stream 248.

The transmitter portion 312 includes a conversion module 314, a modulation parameter module 316, a first up-conversion module 318, a second up-conversion module 320, a combining module 322, and a power amplifier circuit 324. Power amplifier circuitry 324 may include one or more amplifier drivers connected in series and/or in parallel and/or one or more amplifiers connected in series and/or in parallel.

In operation, the conversion module 314 and the modulation parameter module 316 receive the outbound data symbol stream 242, where each symbol may be represented by a hybrid coordinate having an in-phase component and a quadrature component. The conversion module 314 converts the in-phase and quadrature components of the symbol into normalized I326 and normalized Q328 symbols. This can be achieved by setting the amplitude of the in-phase component and the quadrature component to the same value. For example, the in-phase component is A_Isin(ω_d(t)) and the orthogonal component is A_Qcos(ω_d(t)), wherein A_IAnd A_QThe amplitude of the in-phase and quadrature components, respectively. By setting the amplitude A_IAnd A_QAre the same value (e.g. 1 or A)_O) Then the normalized I symbol 326 is sin (ω)_d(t)) and the normalized Q symbol 328 is cos (ω)_d(t))。

The modulation parameter module 316 generates offset (offset) information 330 and transmission property (property) information 332 from the outbound data symbol stream 242. In one embodiment, offset information 330 corresponds to phase information (e.g., φ (t)) of a symbol, which may be calculated by calculating tan-1 (A)_Q/A_I) Thus obtaining the product. Alternatively, the offset information 330 corresponds to frequency information of the symbol.

The modulation parameter module 316 generates the transmission attribute information 332 as a power level setting or amplitude modulation information. For example, if the data modulation method uses phase modulation (e.g., QPSK, GMSK) or frequency modulation (e.g., frequency shift keying) without amplitude modulation, the transmission attribute information 332 will correspond to the power level setting. In an alternative embodiment, the data baseband processing module 232 may generate the power setting.

If the data modulation method used includes both phase modulation and amplitude modulation (e.g., 8-PSK, QAM), or both frequency modulation and amplitude modulation, then modulation parameter module 316 will generate amplitude information. In one embodiment, the amplitude information (e.g., A (t)) is (A)_Q ²+A_I ²) The square root of (a).

The first up-conversion module 318 combines the normalized I symbol 326 and the offset information 330 to produce an offset normalized I symbol 326 (e.g., sin (ω) for example_d(t) + φ (t))). This signal is mixed with an in-phase local oscillator signal 294 having a frequency corresponding to a first frequency band (e.g., 890-915MHz) to produce a first upconverted signal 336 (e.g., 1/2cos (ω) ω_RF(t)-ω_d(t)-φ(t))-1/2cos(ω_RF(t)+ω_d(t) + φ (t))). The second up-conversion module 320 combines the normalized Q symbols 328 and the offset information 330 to produce offset normalized Q symbols (e.g., cos (ω)_d(t) + φ (t))). This signal is mixed with quadrature local oscillator signal 294 corresponding to the first frequency band and filtered to produce second upconverted signal 338 (e.g., 1/2cos (ω) and_RF(t)-ω_d(t)-φ(t))+1/2cos(ω_RF(t)+ω_d(t) + φ (t))). The combining module 322 combines the first and second upconverted signals 336 and 338 to generate an RF signal 340 (e.g., cos (ω) signal_RF(t)+ω_d(t)+φ(t)))。

Power amplifier circuitry 324 amplifies RF signal 340 in accordance with transmit attribute information 332. In one embodiment, the transmission attribute information 332 is a power level setting (e.g., A)_p) Thus, the outbound RF data signal 244 may be A_p*cos(ω_RF(t)+ω_d(t) + φ (t)). In another embodiment, the transmit attribute information 332 is amplitude information (e.g., a (t)), and thus the outbound RF data signal 244 may be represented by a (t) cos (ω)_RF(t)+ω_d(t) + φ (t)).

When the voice data RF IC70 is in one of the above-mentioned auxiliary modes, each of the baseband modules 230 and 232 and the RF sections 236 and 238 can be tested separately. Alternatively, an off-chip baseband module may be employed to generate the outbound voice or data symbol streams 242 or 254, which are then processed by the data or voice RF section 236 or 238. In yet another alternative embodiment, the voice and/or data baseband processing modules 230 and/or 232 may provide the outbound voice and/or data symbol streams 242 or 254 to the off-chip RF section for conversion to RF signals.

The control section 352 provides a voice control communication path 356 for communicating voice control signals between the voice baseband processing module 230 and the voice RF section 238. The voice control signal includes a read bit, address bits, and voice control bits that control the physical content of the message. The voice baseband processing module 230 outputs the read bit and the address bit. The voice baseband processing module 230 may output voice control bits for write operations and the voice RF section 238 may output voice control bits for read operations. Note that the read bit set to 1 is for a read operation and set to 0 represents a write operation. It is also noted that voice control bits are used for voice communications, which correspond to at least some of the control data of the control messages described in "DigRF base and/or RF DIGITALINTERFACE SPECIFICATION", logical, electrical and timing characteristics, EGPRS version, digital interface working group, version 1.12 or later.

The clock portion 354 also provides a data clock communication path 360 for transferring data clock information, such as clock enable, clock signal and strobe signal (strobe), between the data baseband processing module and the data RF portion.

Fig. 20 is a schematic diagram of another embodiment of a voice data RF IC70 that includes a baseband processing module 370, an interface module 374, and an RF section 372. The voice data RF IC70 may be in a voice mode or a data mode. The voice mode may be activated by the user of the communication device 30 by: initiate a mobile phone call, receive a mobile phone call, initiate a walkie-talkie type phone call, receive a walkie-talkie type phone call, initiate a voice recording function, and/or other voice activated selection mechanism. The data mode may be activated by a user of the communication device 30 by: sending a text message, receiving a text message, initiating a web browsing function, receiving a web browsing response, initiating a data file transfer, and/or activating a selection mechanism via other data.

When the voice data RF IC70 is in the voice mode, the baseband processing module 370 converts the outbound voice signal 252 to correspond to a second frequency band (fb) according to one or more of the existing wireless communication standards, the new wireless communication standards, and modified versions and/or extended versions thereof (e.g., WCDMA, etc.)₂) The outbound voice symbol stream 254.

The baseband processing module 370 may generate the outbound voice symbol stream 254 in cartesian coordinates, polar coordinates, or mixed coordinates, depending on the desired format of the outbound voice symbol stream 254. When the voice data RF IC70 is in voice mode, the interface module 374 transmits the outbound voice symbol stream 254 to the RF section 372.

The RF section 372 converts the outbound voice symbol stream 254 into the outbound RF voice signal 256 in accordance with one or more of the existing wireless communication standards, the new wireless communication standards, modifications thereof, and/or extensions thereof (e.g., WCDMA, etc.), wherein the carrier frequency of the outbound RF voice signal 256 is within a second frequency band (e.g., 1920-. In one embodiment, the RF section 372 receives the outbound voice symbol stream 254 in cartesian coordinates. In this embodiment, the RF section 372 mixes the in-phase component of the outbound voice symbol stream 254 with an in-phase local oscillator signal to produce a first mixed signal and mixes the quadrature component of the outbound voice symbol stream 254 to produce a second mixed signal. The RF section 372 combines the first and second mixed signals to produce an upconverted voice signal. The RF section 372 then amplifies the upconverted voice signal to produce the outbound RF voice signal 256. It is noted that the output of the RF section 372 may then require further amplification of power.

In other embodiments, the RF section 372 receives the outbound voice symbol stream 254 in polar or mixed-coordinate fashion. In these embodiments, the RF section 372 modulates the local oscillator signal based on the phase information of the outbound voice symbol stream 254 to produce a phase modulated RF signal. The RF section 372 then amplifies the phase modulated RF signal based on the amplitude information of the outbound voice symbol stream 254 to produce the outbound RF voice signal 256. Alternatively, the RF section 372 may amplify the phase modulated RF signal according to a set power level to produce the outbound RF voice signal 256.

For the dial-in voice signal, the RF section 372 converts the inbound RF voice signal 258, which is carried in the second frequency band (e.g., 2110-2170MHz), into the inbound voice symbol stream 260. In one embodiment, the RF section 372 extracts cartesian coordinates from the inbound RF voice signal 258 to produce the inbound voice symbol stream 260.

When the voice data RF IC70 is in a data mode (e.g., transceiving e-mail, text messages, web browsing, and/or non-real-time data), the baseband processing module 370 converts the outbound data 240 to correspond to a first frequency band (fb) according to one or more of the existing wireless communication standards, the new wireless communication standards, and modifications and/or extensions thereof (e.g., EDGE, GPRS, etc.)₁) The outbound data symbol stream 242. The baseband processing module 370 may perform one or more of scrambling, encoding, constellation mapping, modulation, spreading, frequency hopping, beamforming, space-time block coding, space-frequency block coding, and/or digital baseband to IF conversion to convert the outbound data 240 into the outbound data symbol stream 242. The baseband processing module 370 may generate the outbound data symbol stream 242 in cartesian coordinates, polar coordinates, or hybrid coordinates, depending on the desired format of the outbound data symbol stream 242. The interface module 374 transmits the outbound data symbol stream 242 to the RF section 372.

The RF section 372 converts the outbound data symbol stream 242 into an outbound RF data signal 244 having a carrier frequency in a first frequency band (e.g., 890-915MHz) in accordance with one or more of the existing wireless communication standards, the new wireless communication standards, modifications thereof, and/or extensions thereof (e.g., EDGE, GPRS, etc.). In one embodiment, the RF section 372 receives the outbound data symbol stream 242 in cartesian coordinates. In this embodiment, the RF section 372 mixes the in-phase component of the outbound data symbol stream 242 with an in-phase local oscillation to produce a first mixed signal and mixes the quadrature component of the outbound data symbol stream 242 to produce a second mixed signal. The RF section 372 combines the first and second mixed signals to produce an upconverted data signal. The RF section 372 then amplifies the upconverted data signal to generate an outbound RF data signal 244. Note that further amplification of power may be required after the output of the RF section 372.

In other embodiments, the RF section 372 receives the outbound data symbol stream 242 in polar or hybrid coordinate fashion. In these embodiments, the RF section 372 modulates the local oscillator signal based on the phase information of the outbound data symbol stream 242 to produce a phase modulated RF signal. The RF section 372 then amplifies the phase modulated RF signal based on the amplitude information of the outbound data symbol stream 242 to produce the outbound RF data signal 244.

In this embodiment, the RF section 372, interface module 374, and baseband processing module 370 functions consistent with that previously described with reference to fig. 20.

In this embodiment, the data input interface 182 receives outbound data 240 for a component of the communication device 30. For example, the data input interface 182 may be a keyboard interface, a keypad interface, a touch screen interface, a serial interface (e.g., USB, etc.), a parallel interface, and/or other types of interfaces for receiving data.

The first transmitter section 390 includes a pair of multiplexers and a pair of mixers. The second transmitter section 392 includes a pair of mixers.

When the voice data RF IC70 is in the data mode, the multiplexer of the first transmitter portion 390 provides the in-phase (I) component of the outbound data symbol stream 242 to the first mixer and provides the quadrature (Q) component of the outbound data symbol stream 242 to the second mixer. The first mixer mixes the I component of the data symbol stream 242 with an I component 396 of a Local Oscillator (LO) to provide a first mixed signal.

The frequency of the data LOs 396, 398 corresponds to the carrier frequency of the desired outbound RF data signal 244 (e.g., 890-915MHz of the first frequency band).

A multiplexer between the first and second transmitter sections 390 and 392 provides the first and second mixing signals to a first summer. The first summer sums the first and second mixed signals to produce an outbound RF data signal 244.

When the voice data RF IC70 is in voice mode, the multiplexer of the first transmitter portion 390 provides the in-phase (I) component of the outbound voice symbol stream 254 to the first mixer and provides the quadrature (Q) component of the outbound voice symbol stream 254 to the second mixer. The first mixer mixes the I component of the outbound voice symbol stream 254 with an I component 396 of a Local Oscillator (LO) to provide a first mixed signal. The second mixer mixes the Q component of the outbound voice symbol stream 254 with a Q component 398 of a Local Oscillator (LO) to provide a second mixed signal. The frequency of the data LOs 396, 398 corresponds to the carrier frequency of the desired outbound RF data signal 244 (e.g., 890-915MHz of the first frequency band).

A multiplexer between the first and second transmitter sections 390 and 392 provides the first and second mixing signals to the second transmitter section 392. The first mixer mixes the first mixed signal with an in-phase (I) component 400 of a voice/data local oscillation (V-D LO) to generate a third mixed signal. The second mixer mixes the second mixing signal with a quadrature (Q) component 402 of a voice/data local oscillation (V-D LO) to generate a fourth mixing signal. The frequency of the V-D LOs 400, 402 corresponds to the carrier frequency of the desired outbound RF voice signal 256 (e.g., 1920-1980MHz of the second band) minus the carrier frequency of the RF data 244 (e.g., 890-915MHz of the first band). For example, the frequency range of the V-D LO 400 is between 1010 and 1065 MHz.

The second summer sums the third and fourth mixed signals to produce an outbound RF speech signal 256.

The adjustable antenna interface 52, 72, and/or 74 connects the first antenna 764 to the RF circuitry to receive the inbound RF signals when the first multi-mode (MM) state of the second antenna control signal 752 is active. In these modes, the inbound and outbound RF signals have carrier frequencies within a first frequency band to which the first antenna and tunable antenna interfaces 52, 72, and/or 74 are tuned.

The adjustable antenna interface 52, 72, and/or 74 connects the second antenna 766 to the RF circuitry to transmit a second outbound RF signal when the second multi-mode (MM) state of the first antenna control signal 750 is active.

In this embodiment, first and second antennas 760 and 762 are shared for both transmission and reception, but diversity is employed, where antennas 760 and 762 are physically separated by 1/4 wavelengths or other particular distance, so that if the signal strength is zero at one of antennas 760 and 762 due to multipath fading, the other antenna will not experience such a 0 attenuation at that time.

For example, if the antenna is a half-wavelength antenna for a particular frequency within a frequency band but the RF signal is within the frequency band but not exactly coincident with the frequency, antenna tuning circuit 782 adjusts the effective length of the antenna to the desired half-wavelength. As an example, assume that the particular frequency is 900MHz, but in practiceAt 960MHz for the RF signal, the half wavelength is 16.67 centimeters (cm) (i.e., 0.5 x (3 x 10)⁸)/(900×10⁶)). However, for a 960MHz signal, the desired half wavelength is 15.63 cm. In this example, the antenna tuning circuit 782 (which includes one or more inductors and one or more capacitors) adjusts its resonant frequency to the actual frequency of the inbound or outbound signals (e.g., 960MHz), so that the effective wavelength of the antenna is adjusted to 15.63cm, although the actual length is 16.67 cm.
