The radio frequency path in mobile terminals is often used to transmit and receive communication signals. The current radio frequency path includes transceivers, power amplifiers, duplexers, impedance matching networks, couplers and feedback paths. During the transmission process, the transceiver generates The low-power transmission signal is amplified by the power amplifier, and then transmitted to the coupler through the duplexer. The coupler couples the transmission signal to obtain two output signals, one of which is modulated and transmitted through the antenna. out, the other output signal is the feedback power and is fed back to the transceiver end through the feedback path; during the reception process, the signal received by the antenna is demodulated and input into the coupler for coupling processing, and the coupled signal is duplexed return to the transceiver side.
