Abstract:
Disclosed is a radio frequency circuit, a method of transmitting and receiving radio frequency signals, and a wireless communication device. The radio frequency circuit includes a first radio frequency amplifier, a second radio frequency amplifier, a first channel switch, a first low noise amplifier, a second low noise amplifier, and a second channel switch; the first radio frequency amplifier and the second radio frequency amplifier are connected with a plurality of antennas through the first channel switch, respectively, and are connected with a plurality of SRS antennas through an SRS switch in the first channel switch; the first low noise amplifier and the second low noise amplifier are connected with the plurality of antennas through the first channel switch, respectively, and are connected with a receiver through the second channel switch, respectively; wherein, the first radio frequency amplifier or the second radio frequency amplifier transmits one channel of radio frequency transmission signals to realize one-channel transmission, and the first low noise amplifier and the second low noise amplifier simultaneously receive radio frequency reception signals to realize two-channel reception.
