A signal receiving circuit amplifies a radio frequency signal by using a first radio frequency amplifier, outputs a first amplified signal in a same phase, amplifies the radio frequency signal by using a second radio frequency amplifier, and outputs a second amplified signal at an inverse phase. A first mixer mixes a first local oscillator signal with the first amplified signal to obtain a first frequency mixing signal, and a second mixer mixes a second local oscillator signal with the second amplified signal to obtain a second frequency mixing signal, where a phase of the first local oscillator signal is opposite to a phase of the second local oscillator signal. After adding the first frequency mixing signal and the second frequency mixing signal, an output interface outputs the first frequency mixing signal and the second frequency mixing signal.
