Radio frequency circuit and terminal device

A terminal device, comprising a radio frequency circuit, wherein the radio frequency circuit comprises a radio frequency front-end module, a switch module, and an antenna module;

• the radio frequency front-end module comprises a radio frequency transceiver and a first processing module connected to the radio frequency transceiver;
• the antenna module comprises an antenna for receiving or transmitting a radio frequency signal;
• a first terminal of the radio frequency transceiver is connected to a first terminal of the first processing module, and a second terminal of the radio frequency transceiver is connected to a second terminal of the first processing module;
• a third terminal of the first processing module is connected to a first terminal of the switch module;
• a second terminal of the switch module is connected to the antenna module;
• the first terminal of the radio frequency transceiver is configured to transmit a signal of a first network;
• the second terminal of the radio frequency transceiver is configured to transmit a signal of a second network;
• and
• the first processing module is configured to transmit the signal of the first network and the signal of the second network;
• wherein
• the first processing module comprises a first processing sub-module and a second processing sub-module;
• the first terminal of the switch module comprises a fifth sub-terminal and a sixth sub-terminal;
• the first terminal of the radio frequency transceiver is connected to a first terminal of the first processing sub-module, and the second terminal of the radio frequency transceiver is connected to a first terminal of the second processing sub-module;
• a second terminal of the first processing sub-module is connected to the fifth sub-terminal;
• a second terminal of the second processing sub-module is connected to the sixth sub-terminal;
• a third terminal of the first processing sub-module is connected to a third terminal of the second processing sub-module;
• the first processing sub-module is configured to transmit the signal of the first network and/or the signal of the second network;
• and
• the second processing sub-module is configured to receive at least one of the signal of the first network or the signal of the second network, or is configured to receive the signal of the first network and transmit the signal of the second network, or is configured to transmit the signal of the second network.
