摘要
描述了一种覆盖200-350 GHz范围的低温接收机。两个肖特基二极管混频器覆盖这个范围，混频器和FET中频放大器冷却到20 K。LO功率由倍频器/三倍器提供，使用马丁-普普莱特干涉仪作为LO信号双工器。在225 GHz时，系统的最佳温度为710 K SSB，在348 GHz时达到2000 K。
A cryogenic receiver covering the 200-350 GHz range is described. Two Schottkydiode mixers cover this range, with the mixers and FET IF amplifier cooled to 20 K. LO power is provided by a frequency doubler/tripler, with a Martin-Puplett interferometer used as the LO-signal diplexer. The best system temperature is 710 K SSB at 225 GHz, rising to 2000 K at 348 GHz.
