Abstract

A technique is presented for determining the quality of tunable short circuits used as backshorts in waveguide mixers. A backshort, suitable for use in a reduced height 345 GHz Schottky mixer block, has been fabricated in a novel manner and the VSWR determined, using our technique, to be >90 at room temperature.
