The mixer circuit includes a mixer, an LO matching circuit inserted between an LO signal terminal and a first terminal of the mixer, an IF matching circuit inserted between the IF signal terminal and a second terminal of the mixer, and an RF matching circuit inserted between an RF signal terminal and a third terminal of the mixer. In the RF matching circuit, a reflection characteristic is set such that a minimum value of reflection loss appears on a high-frequency side of the frequency of the LO signal.
