ABSTRACT:
A feed network parallel superconductive tunnel junction circuit that acts as a doubly balanced mixer and can be utilized as a millimeter wave satellite communications link. A quadrature-fed mixer circuit relies on a network of 90 degree couplers to feed signal and local oscillator power to four identical SIS detectors where SIS is a superconductor-insulator-superconductor layer construction. Power applied to either port is split equally to each detector, and the relative phase relationship of the signal and the LO is preserved. By selecting the appropriate polarity of the dc junction bias, the detected IF output of the SIS detectors adds coherently.
