Abstract
A double-balanced mixer circuit which consumes less power, and is capable of operating on a low voltage power source, because an output of a first signal having a phase lag of 90.degree. from a first frequency signal and an output of a second signal having a phase lead of 90.degree. over the first frequency signal are provided by means of a first phase shifter, an output of a third signal having a phase lag of 90.degree. from a second frequency signal and an output of fourth signal having a phase lead of 90.degree. over the second frequency signal are provided by means of a second phase shifter, thereby generating a radio frequency signal by mixing the first signal and the third signal in a first dual gate circuit, and generating a radio frequency signal by mixing the second signal and the fourth signal in a second dual gate circuit.
