Abstract

A GaAs switching mixer (10) receives an information signal (16) and an injection signal (20) to provide an intermediate frequency signal. The injection signal (20) controls enhancement mode GaAs devices (18 and 22) so as to minimize the required injection drive level and harmonic distortion.
