Paper Abstract

A quasioptical Josephson detector with resistively shunted superconducting tunnel junctions of superconductor-insulator-superconductor (SIS) type and different integrated matching circuits for mm waveband region has been designed, fabricated and experimentally studied. A special quasioptical cryogenic probe has been designed and fabricated for measurements of microwave response of such integrated receiving structures. For low-frequency matching a cold transformer has been used at the output port. Many efforts have been made for reducing the external noise influence on Josephson junction IV curve. Quasioptical beamguide has been optimized and adjusted using Bi bolometers evaporated instead of Josephson junctions in the center of planar antenna. Beampatterns of several types of planar antennas, including self-complementary and non-complementary logarithmic spiral and log-periodic antennas, have been measured using the same technique.
