Possible implementations of the wireless communication device according to one or more of the embodiments described above are described by way of example below.
Based on the defects of the prior art, the application provides a design scheme for realizing Wi-Fi/BT simultaneous transmission through a power divider, and the core idea is that signal separation and aggregation between Wi-Fi and BT are realized through the power divider, and when two signals are aggregated together at a transmitting end, the two signals respectively lose 3dB and finally reach a transmitting port to realize transmission, as shown in fig. 8, a block diagram of the scheme is provided, wherein a first power divider is arranged at output ends of Wi-Fi transmission and BT transmission, is respectively connected with two ports of the first power divider, and finally outputs to an antenna port.
As shown in fig. 9, in a scenario where Wi-Fi signals and BT signals are transmitted simultaneously, the wireless transceiver controls the SP4T (i.e., a single-pole four-throw switch, corresponding to the first switch) to turn on the connection between the wireless transceiver, PA Wi-Fi, SAW1, the first power divider, couper (i.e., a coupler) and the antenna, and the wireless transceiver controls the SP4T (i.e., a single-pole four-throw switch) to turn on the connection between the wireless transceiver, SPDT1, PA BT, the first power divider, couper (i.e., a coupler) and the antenna, so that the wireless transceiver transmits the first Wi-Fi signals through the Wi-Fi transmitting port, amplifies the PA Wi-Fi signals through the PA Wi-Fi, then filters the Wi-Fi signals through the SAW1, and outputs the first BT signals through the BT transmitting port to the first power divider, the first power divider aggregates the processed first Wi-Fi signals and the first BT signals, transmits the aggregated first BT signals to Couper, and transmits the aggregated first BT signals through the Couper to the antenna (i.e., wi-Fi/34) through the ANT port after further processing.
Under the scene of receiving Wi-Fi signals and BT signals at the same time, the wireless transceiver controls the SP4T (namely a single-pole four-throw switch) to conduct the connection (weak signal scene) of the antenna, the SAW2, the LNA, the second power divider and the wireless transceiver, or conduct the connection (strong signal scene) of the antenna, the second power divider and the wireless transceiver, so that the aggregate signals received by the antenna are processed by the SAW2 and the LNA and then output to the second power divider, or the aggregate signals received by the antenna are directly output to the second power divider, the second power divider splits the aggregate signals into a third Wi-Fi signal and a third Bluetooth signal, and the third Wi-Fi signal and the third Bluetooth signal are respectively transmitted to the wireless transceiver through a Wi-Fi/BT receiving port and a BT receiving port.
As shown in fig. 10, on the basis of fig. 8, SPDT2 (corresponding to the second switch) is added to the output end of SAW1, and SPDT2 is connected with the first power divider and SP4T respectively, so that when Wi-Fi signals are transmitted independently, wi-Fi signals are directly output to the antenna without passing through the first power divider, that is, the influence of the first power divider on Wi-Fi signals is eliminated, and therefore no loss of Wi-Fi signals is ensured.
As shown in fig. 11, when Wi-Fi signals are transmitted separately, the wireless transceiver controls SPDT2 and SP4T to turn on the connection of the wireless transceiver, PA Wi-Fi, SAW1, couper (i.e., coupler), and the antenna, so that the wireless transceiver transmits a second Wi-Fi signal to the antenna through the ANT port after processing the second Wi-Fi signal through the PA Wi-Fi, SAW1, couper through the Wi-Fi transmission port. Thus, the performance of the Wi-Fi mode can be further improved.
When the BT signal is transmitted separately, the wireless transceiver controls SPDT1 (corresponding to the third switch) and SP4T to turn on the connection (strong signal scenario) of the wireless transceiver, couper (i.e., coupler) and the antenna, so that the wireless transceiver transmits the second BT signal to the antenna through the ANT port after processing the second BT signal through the Wi-Fi transmission port Couper. Or an SPDT4 (corresponding to a fourth switch) is added to the output end of the PA BT, and the SPDT4 is connected to the first power divider and the SP4T (not shown in fig. 11), and the wireless transceiver controls the SPDT1, SPDT4, and SP4T to conduct the connection (weak signal scenario) between the wireless transceiver, the PA BT, couper (i.e., coupler), and the antenna, so that the wireless transceiver processes the second BT signal through the Wi-Fi transmitting port through the PA BT, couper, and transmits the processed second BT signal to the antenna through the ANT port.
Therefore, wi-Fi/BT access simultaneous transmission can be realized on the basis of the existing antenna device by utilizing the power divider, and the best performance, the best cost and the best area are realized.
