A Quasi-Optical Schottky Barrier Diode Mixer For The Submillimeter Region

Heterodyne measurements of Schottky diode performance at room temperature were carried out at wavelengths ranging from 919 μm to 372 μm. Coupling structure parameters were varied to achieve optimum coupling efficiency. First measurements on the performance of alternative beam-combining structure replacing the quasioptical diplexer are presented.
