Abstract

A superconductive tapped delay line, circuits comprising superconductor-insulator-superconductor (SIS) mixers, an L-C integrator, and a tunnel junction comparator, and superconductive digital address encoders have been integrated into a 14-channel analog signal correlator. This 25×38 mm circuit was fabricated using a Nb/Nb₂O₃/Pb tunnel junction process. Preliminary testing of this device indicates the ability to process long duration, wideband waveforms with time-bandwidth products equal to 6000
