The physical principles of operation of terahertz HEB mixers are presented, their manufacturing from ultrathin NbN films, the main HEB-mixer parameters and their measurement techniques are discussed, and practical terahertz radioastronomy projects based on heterodyne receivers with HEB mixers are considered. %K NbN HEB mixers %R 10.1023/B:RAQE.0000024991.65949.d6 %U https://link.springer.com/article/10.1023/B:RAQE.0000024991.65949.d6 %U https://doi.org/10.1023/B:RAQE.0000024991.65949.d6 %P 604-617
