采用工作在4.5K的铅合金超导隧道结混频器，研制了射电天文低噪声接收机。它们已被用于85-115-GHz天文学，双边带接收机噪声温度在70和200 K之间。本文描述了结制造和接收器构造、操作和性能。
Low-noise receivers for radio astronomy have been built using Pb alloy superconducting tunnel junction mixers operating at 4.5 K. They have been used for 85-115-GHz astronomy with double-sideband receiver noise temperature between 70 and 200 K. Junction fabrication and receiver construction, operation, and performance are described herein.
