Abstract
A harmonic mixer that suppresses the degradation of the conversion efficiency is disclosed. That harmonic mixer includes an input transmission line, an output transmission line, and two transistors connected in parallel between the input transmission line and the output transmission line. Two transistors are complementarily driven by a local signal LO and generate an output signal RF with frequencies of 2×fLO±fIF, where fLO and fIF are frequencies of a local signal LO and an intermediate signal IF.
