The quasi-optical NbN superconducting HEB mixer is cryogenically cooled bya 4-K close-cycled refrigerator. Its receiver noise temperature and conversion gain are thoroughly investigatedfor different LO pumping levels and dc biases. The lowest receiver noise temperature is found to be approxi-mately 1200 K, and reduced to about 445 K after correcting theloss of the measurement system. The stabilityof the mixer{\textquoteright}s IF output power is also demonstrated.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=1482), last updated on Mon, 17 May 2021 23:36:20 -0500", issn="1931-7360", doi="10.2529/PIERS041203233704", opturl="http://piers.mit.edu/piersonline/piers.php?year=2005&volume=1&number=5&page=587", opturl="https://doi.org/10.2529/PIERS041203233704" }
