Research on Superconductive Signal-Processing Devices.
Abstract
A new technology utilizing superconductive components to realize convolvers and correlators that are capable of processing analog signals having bandwidths from 2-20 GHz is being developed. The technology has two key features: (1) low-loss and low-dispersion electromagnetic striplines provide tapped delay on compact substrates; and (2) superconductive tunnel junctions provide efficient low-noise mixing and high-speed sampling circuits. A convolver with a time-bandwidth product of 28 has been demonstrated. Projections indicate that superconductive technology should support analog devices with time-bandwidth products of 1000 or greater. Originator-Supplied keywords include: convolver, time integrating correlator, ring correlator, convolution, and supercondcutive signal processing.
