Superconductive electronics-current status and promise for the future

Summary form only given. The author has surveyed the current state of the art of superconductive electronics. Emphasis was placed on circuits employing low-temperature superconducting materials such as lead (critical temperature T/sub c/=7 K) and two refractory materials, niobium (T/sub c/=9 K) and niobium nitride (T/sub c/=16 K). Efforts have been made to integrate these devices with a multilithic antenna on a 1-cm silicon chip to form a superconductive monolithic integrated 100-GHz heterodyne receiver. The goal of this effort was to develop a fully superconductive phased-array receiver. The author has also examined the status of further research in Josephson junction technology and phased-locked arrays of these junctions.<>
