The second input to the output of the switching module 107 is in an off state.

In this embodiment, when the radio frequency circuit 100 operates in any sub-operating mode of the first operating mode, the first input terminal and the output terminal of the switch module 107 need to be in an on state, and the second input terminal and the output terminal of the switch module 107 need to be in an off state, so as to ensure that the first power supply module 105 can supply power to the second transceiver module 102, and the second power supply module 106 can supply power to the third transceiver module 103 or the fourth transceiver module 104.

The switch module 107 includes a first switch 1072 and a second switch 1074, and when the rf circuit 100 operates in any sub-operation mode of the first operation mode, the first switch 1072 is controlled to be in a conducting state, so that the first input terminal to the output terminal of the switch module 107 are in a conducting state, and the second switch 1074 is in a disconnecting state, so that the second input terminal to the output terminal of the switch module 107 are in a disconnecting state.

It should be noted that, when the first input terminal and the output terminal of the switch module 107 are turned on, the first power supply module 105 is controlled to selectively supply power to the first transceiver module 101 and the second transceiver module 102 by controlling on/off states of the switch devices in the first transceiver module 101 and the second transceiver module 102, and the second power supply module 106 is controlled to selectively supply power to the third transceiver module 103 and the fourth transceiver module 104 by controlling on/off states of the switch devices in the third transceiver module 103 and the fourth transceiver module 104.

Specifically, when the switching device in the first transceiver module 101 is in an off state and the switching device of the second transceiver module 102 is in an on state, the first power supply module 105 supplies power to the second transceiver module 102. When the switching device in the first transceiver module 101 is in an on state and the switching device of the second transceiver module 102 is in an off state, the first power supply module 105 supplies power to the first transceiver module 101. When the switching device in the third transceiver module 103 is in an off state and the switching device of the fourth transceiver module 104 is in an on state, the second power supply module 106 supplies power to the fourth transceiver module 104. When the switching device in the third transceiver module 103 is in an on state and the switching device of the fourth transceiver module 104 is in an off state, the second power supply module 106 supplies power to the third transceiver module 103.
