Practical low-noise quasiparticle receiver for 80-100 GHz
Abstract
A heterodyne receiver for millimeter-wave radio astronomy, which uses a quasiparticle mixer with junctions of Pb/Bi/In-oxide-Pb/Bi has been tested. A receiver noise temperature of around 100 K double sideband has been measured with a number of different junctions. For one junction, the best receiver temperature obtained was 73 K, and the mixer conversion loss was less than 5.8 dB double sideband.
