RADIO FREQUENCY FRONT END MODULE, RADIO FREQUENCY APPARATUS AND COMMUNICATION DEVICE

WIPO Patent Application WO/2023/050421

A1

Provided in the present application are a radio frequency front end module, a radio frequency apparatus and a communication device. The radio frequency front end module may be coupled to a radio frequency transceiver circuit without the need for an additional switch, thereby reducing the board-level cost of a communication device and increasing the integration level. A first port is coupled to a sending branch and a receiving branch by means of a switching module, and a second port is coupled to the sending branch and the receiving branch by means of the switching module. The first port supports the transmission of a signal of a first frequency band, and the second port supports the transmission of a signal of a second frequency band, wherein the first frequency band is different from the second frequency band. The receiving branch supports the receiving processing of signals of the first frequency band and the second frequency band, and the sending branch supports the sending processing of the signals of the first frequency band and the second frequency band. The switching module is used for selectively transmitting, to the first port or the second port, the signals that have been processed by the sending branch, or selectively transmitting, to the receiving branch, a signal that is received by the first port or a signal that is received by the second port.
