摘要:

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