Quasioptical circuits relating to frequency multipliers.

Description of the various major components useful in a 30- to 60-GHz varactor doubler circuit employing quasi-optical techniques. A description is given of the required directional filters, waveguide tuners, and varactor mounts. An attempt is made to determine the potential efficiency of various quasi-optical multiplier mounts and also to compare the efficiency obtainable by quasi-optical techniques with that achievable in standard-waveguide multiplier mounts.
