Abstract: Embodiments of the present invention provide a receiver and a wireless communications apparatus. The receiver includes: an attenuation circuit, configured to receive an input signal, and obtain a first signal according to the input signal; a low-noise amplification circuit, configured to receive the first signal, and obtain a second signal according to the first signal; an orthogonal down-frequency conversion circuit, configured to receive the second signal, and process the second signal to obtain an output signal; and a control circuit, configured to separately control the attenuation circuit and the low-noise amplification circuit according to power of an interference signal included in the output signal, so as to determine whether the attenuation circuit attenuates the input signal and whether the low-noise amplification circuit amplifies the first signal.
