Abstract
A mixer circuit contains a first terminal and a second terminal to which a first differential input signal is applied, and an active element switching a short-circuit between the first terminal and the second terminal. By driving the active element by a second differential input signal having a predetermined frequency, the first terminal and the second terminal are intermittently short-circuited at twice the frequency of a predetermined frequency.
