In this paper, a phononcooled NbN HEB mixer (quasioptical type) is thoroughly characterized under such a cooling circumstance. The effects of mechanical vibration, electrical interference, and temperature fluctuation of a two-stage Gifford-McMahon 4 Kelvin refrigerator upon the characteristics of the phononcooled NbN HEB mixer are investigated in particular. Detailed measurement results are presented.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=1469), last updated on Mon, 17 May 2021 17:10:31 -0500", issn="1558-2515", doi="10.1109/TASC.2005.849891", opturl="https://doi.org/10.1109/TASC.2005.849891" }
