In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, the act of approaching an object on the touch screen without being in contact so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called “contact touch”. The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have.

When the RFIC 250 is configured as a 4G/5G integrated circuit, it is advantageous in terms of synchronization between 4G/5G circuits, and also has an advantage that control signaling by the modem 400 can be simplified.

When the RFIC 250 is configured as a 4G/5G separate type, it may be referred to as a 4G RFIC and a 5G RFIC, respectively. In particular, when the difference between the 5G band and the 4G band is large, such as when the 5G band is configured as a millimeter wave band, the RFIC 250 may be configured as a 4G/5G separate type. When the RFIC 250 is configured as a 4G/5G separate type, there is an advantage that RF characteristics can be optimized for each of the 4G band and the 5G band.

Even when the RFIC 250 is configured in a 4G/5G separate type, the 4G RFIC and the 5G RFIC are logically and functionally separated, and it is also possible to be physically implemented in one chip.

According to an embodiment, the application processor 500 may control the operation of each component of the electronic device 100 . Specifically, the application processor 500 may control the operation of each component included in the electronic device 100 through the modem 400 .

For example, the modem 400 may be controlled through a power management IC (PMIC) for low power operation of the electronic device 100 .

According to an embodiment, in the multi-transceiving system of FIG. 2 , a transmitter and a receiver of a radio system may be integrated and implemented as one transceiver. When implemented as one transceiver unit as described above, there is an advantage that a circuit part integrating two types of system signals in the RF front-end can be removed. In addition, since the front-end components can be controlled by the integrated transceiver, the front-end components can be integrated more efficiently than when the transmission/reception system is separated for each communication system. As described above, when the transmitter and the receiver are separated for each communication system, it is impossible to control other communication systems, and thus system delay may be aggravated, making efficient resource allocation impossible. On the other hand, the multiplex transmission/reception system shown in FIG. 2 has the advantage that it is possible to control other communication systems as needed, and it is possible to minimize system delay due to the uncontrollability of the multiplex communication system, so that efficient resource allocation is possible.

The filter 232 may include a transmit filter connected to a first output port of the duplexer 231 and a receive filter connected to a second output port of the duplexer 231 . According to another embodiment, the filter 232 may be configured to pass only a signal of a transmission band or only a signal of a reception band according to the control signal.

The switch 233 is configured to transmit either only a transmit signal or a receive signal. In an embodiment of the present invention, the switch 233 may be configured in a single pole double throw (SPDT) type to separate a transmission signal and a reception signal in a time division duplex (TDD) method. In this case, the transmission signal and the reception signal are signals of the same frequency band, and accordingly, the duplexer 231 may be implemented in the form of a circulator.

According to another embodiment, the switch 233 is also applicable to a time division duplex (TDD) scheme. In this case, the switch 233 may be configured in the form of a double pole double throw (DPDT) to connect or block the transmission signal and the reception signal, respectively. According to various embodiments, since the transmission signal and the reception signal can be separated by the duplexer 231 , the switch 233 is not necessarily required.

According to an embodiment, the electronic device 10 may further include a modem 400 corresponding to the controller 180 . In this case, the RFIC 250 and the modem 400 may be referred to as a first controller (or first processor) and a second controller (second processor), respectively.
