A Wideband RF and Wideband IF DSB SIS Mixer
Paper in proceeding, 2024
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.
