Dual‐frequency (40/100 GHz) SIS receiver for nobeyama millimeter‐wave array

Masayuki Yamamoto, K. Yamaji, Keiichi WATAZAWA +3 more

Abstract The authors developed a dual‐frequency (40/100 GHz) SIS receiver with SIS quasi‐particle tunneling junction element as the mixer, for use in the millimeter‐wave array at Nobeyama Radio Observatory, National Astronomical Observatory. The SIS element used is an array composed of four series‐connected Nb/Al‐AlOx/Nb junctions. The receiver is refrigerated to 4.3 K by a closed‐cycle He refrigerator. The receiver realized a very low receiver noise temperature for a wideband, such as 50 to 80 K for 43 to 49 GHz, and 60 to 100 K for 86 to 115 GHz. A wide dynamic range is also realized. At 40 Ghz, the saturation noise temperature is 2000 to 3000 K, compared with the wideband noise. These results indicate that the SIS array element can effectively improve the mixer saturation level without degrading the receiver performance.

A Wideband RF and Wideband IF DSB SIS Mixer

Igor Lapkin, Victor Y. Belitsky, Alexey Pavolotsky +9 more

The ALMA 2030 Roadmap document calls for a new generation of receivers for ALMA. Such Wideband Sensitivity Upgrade, WSU, aims to improve the existing receiver bands of ALMA with prospectively 4-times wider IF bandwidth and possibly a wider RF bandwidth. In order to explore a possibility to make wideband RF and simultaneously wideband IF receiver, we constructed and built a DSB SIS mixer covering the RF band 210-380 GHz. The mixer exhibits a 4 – 20 GHz IF band and produces non-corrected nose temperature between 3hf/k and 4 hf/k averaged over the IF band.
