Abstract

A new technology utilizing superconductive components for pulse compressors and convolvers that are capable of processing analog signals having bandwidths from 2-20 GHz will be described. The technology has two key features: low-loss and low-dispersion electromagnetic striplines which provide tapped delay on compact substrates; and superconductive tunnel junctions which provide efficient low-noise mixing and high-speed sampling circuits. A pulse expander/compressor pair (1) and a convolver (2) with respective time-bandwidth products of 86 and 21 have been demonstrated.
