Abstract :
A superhetrodyne receiver operating in the frequenCY range 350 - 400 GHz has been constructed. The mixer consists of a low capacitance GaAs Schottky barrier diode, contacted by means of an ultra small inductance spring, mounted across a reduced height waveguide which is fed by a corrugated horn. The quasi-optical diplexer consists of a modified polarization rotating Michelson interferometer and the local oscillator is a Carcinatron. The overall receiver design is discussed and results of measured performance will be presented.
