Paper Abstract

Josephson junctions (JJ) mixers have been developped and in the millimeter (185-270 GHz) and in the sub-millimeter range (345 GHz, 1000 GHz). Pointcontact devices have shown the best noise temperatures (Tsys = 420 K at 230 GHz) but are unreliable for practical operations. The developped planar junctions have gown so far competitive performance with respect to cooled Schottky barrier diode mixers e.g.. Tsys = 1600 K at 345 GHz.
