Abstract

A 230 GHz mixer receiver has been constructed using (Pb/In/Au) - (Pb/Bi) SIS junctions fabricated using the Dolan bridge method and thermal oxidation. The mixer block is of conventional design with reduced height waveguide and contacting backshort. Preliminary results indicate a receiver noise temperature <1000K (DSB).
