摘要

接收器的频带为40-50 GHz, 215-245 GHz和460-490 GHz。所有使用肖特基势垒二极管混频器，冷却到15 K，在波导结构。在两个较高的频率范围内，需要一个透镜来匹配望远镜和馈电喇叭。报道了前两个接收机的天线和天文结果。

Three Facility Low-Noise Receivers for Millimeter and Submillimeter Radio-Astronomy

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.
