PURPOSE: To provide a frequency converter that can reduce distortion without much increasing the operating current. CONSTITUTION: In the frequency converter, a main mixer 3 for applying frequency conversion to an input RF signal with a local signal at a prescribed conversion gain and a distortion compensation mixer 4 for applying frequency conversion to the input RF signal with the local signal at a conversion gain lower than that of the main mixer 3 are arranged in parallel, and an adder circuit 5 sums an output signal from the main mixer and an output signal from the distortion compensation mixer in a relation of the inverted phase to each other to generate a frequency conversion output signal. |
