Abstract :
Receivers are reported for the frequency bands 40-50 GHz, 215-245 GHz and 460-490 GHz. All use Schottky barrier diode mixers, cooled to 15 K, in a waveguide construction. In the two upper frequency ranges, a lens is required to match the telescope to the feed horn. Antenna and astronomical results on the first two receivers are reported.
