Heterodyne mixing at 70 GHz with superconductor-insulator-superconductor tunnel junctions
Abstract
A laboratory heterodyne receiver working at 70 GHz was built up using superconductor-insulator-superconductor tunnel junction as mixing element. Single sideband conversion loss LC as low as 1.92±0.23 and mixer noise temperature TM of less than 100 K have been achieved while local oscillator pump power is 4·10-8W.
