Abstract

A wideband enhancement sum mixer is shown to comprise a pair of matched GaAs diodes operative with a printed circuit wherein a portion of at least the sum signal, i.e., the sum of a radio frequency signal and a local oscillator signal, is caused to be mixed with the second harmonic of the local oscillator signal to produce an intermediate frequency signal in phase with the intermediate frequency signal resulting from mixing of the radio frequency signal and the local oscillator signal.
