First Results for a 2.5 THz Schottky Diode Waveguide Mixer

Abstract

A Schottky diode mixer has been realised at 2.5 THz in a waveguide configuration. Measured RF performance is comparable to that obtained using the conventional corner reflector mount and the waveguide mixer has the added benefits of excellent beam efficiency and circuit tuning capability. In addition, the structure has been demonstrated to be reliable and rugged. The mixer design and construction is briefly described and first RF performance results are presented.
