Abstract
A radio frequency transceiver device includes an antenna unit, a first matching circuit, a receiver circuit, a second matching circuit, a transmitter circuit, and an auxiliary circuit. The receiver circuit includes a mixer unit. The auxiliary circuit includes a first transformer coil and a second transformer coil. The first matching circuit and the receiver circuit are configured to form a first signal reception channel to receive, process, and transmit the first radio frequency signal to the mixer unit when the first radio frequency signal is a high gain radio frequency signal. The second matching circuit and the auxiliary circuit are configured to form a second signal reception channel to receive, process, and transmit the first radio frequency signal to the mixer unit when the first radio frequency signal is a middle-low gain radio frequency signal. Another radio frequency signal transceiver device further includes a third matching circuit.
