Abstract :
SIS harmonic mixer based on quasioptical structure with equiangular planar spiral antenna was investigated. SIS junction capacitance was resonated out by integrated circuit elements. Conversion losses, saturation power and noise were measured for quantum and nonquantum LO frequency operation. Nb-Al2O3-Nb SIS junctions and 75 GHz, 37.5 GHz, 25 GHz and 9.4 GHz LO frequencies (1, ¿, ¿ and ¿ of signal frequency 75 GHz) were used.
