Abstract:
A heterodyne receiver using a SIS waveguide mixer with integrated horn and single backshort tuner has been built. It has been used for a series of airborne measurements of atmospheric trace gases, like HCl and C10, above northern Europe during the winter of 1993/94. The receiver is suitable for measurements in the range of 625-720 GHz and shows stable performance in an airplane combined with high sensitivity. The best achieved noise temperature in the laboratory was TDSB=310 K at 708 GHz and an all-over single sideband system noise temperature of TSSB=1500 K at 625 GHz in the airplane.
