A receiver circuit includes: a local signal generation circuit that generates a local signal; and a test signal generation circuit that generates a test signal having a frequency close to a frequency of the local signal, wherein the test signal generation circuit includes an oscillator that generates the test signal, a mixer that mixes the local signal with an output of the oscillator to generate a low-frequency signal which is a difference signal between the local signal and the output of the oscillator, a phase detector that detects a phase difference between the low-frequency signal output by the mixer and a reference signal, and a filter that extracts a low-frequency component from an output of the phase detector, and controls an oscillation frequency of the oscillator by using an output of the filter.
