Abstract

In a microwave push-pull frequency converter having the form of a waveguide for effecting frequency conversion of a broadband microwave signal, which converter includes a converter module composed of a waveguide section and a pair of semiconductor mixer elements disposed in the waveguide section for effecting frequency conversion between a high frequency microwave signal and a low frequency microwave signal without intermediate frequency conversion, the converter further including a waveguide filter for the low frequency microwave signal connected to one side of the module, the waveguide filter includes a plurality of ridged waveguide sections and a plurality of blocking waveguide sections interposed between, and coupling, the ridged waveguide sections, and the converter module includes fastening devices supporting the semiconductor mixer elements and configured to give the coverter module the form of a ridged waveguide which permits the high and low frequency microwave signals to pass in a single mode.
