ABSTRACT
Develops a low-noise superconductor-insulator-superconductor quasiparticle mixer with niobium titanium nitride (NbTiN) thin-film microstrip tuning circuits and hybrid Nb/AlN/NbTiN tunnel junctions. Use of a quasioptical configuration with a planar twin-slow antenna feeding a two-junction tuning circuit; Uncorrected double-sideband receiver noise temperature.
