Abstract
We have made heterodyne radiometric measurements with GaAs Schottky diode mixers, mounted in a corner-reflector configuration, over the spectral range 170 ..mu..m to 1 mm. At 400 ..mu..m, system noise temperatures of 9700 K DSB (NEP=1.4 x 10/sup -/19 W/Hz) and mixer noise temperatures of 5900 K have been achieved. This same quasioptical mixer has also been used to generate 10/sup -/7 W of tunable radiation suitable for spectroscopic applications.
