85--115-GHz Receivers for Radio Astronomy

D. P. Woody, Ronald Earle Miller, Michael J. Wengler

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.

A 100 - 115 GHz SIS receiver for radio astronomy

Hideo Ogawa

A 110 GHz superconductor insulator superconductor (SIS) tunnel junction receiver has been developed and used in regular astronomical observations on the 4m radio telescope at the Department of Astrophysics, Nagoya University. The SIS junction consists of a sandwich structure of Nb/AlOx/Nb, and is cooled to 4.2K with a closed cycle He-gas refrigerator. The receiver exhibits a best double side band noise temperature of 17±2 K at 110GHz. The receiver has a good response over this input frequency range of 98-115 GHz.
