Abstract
The use of SIS (Superconductor-Insulator-Superconductor) devices as the mixing element in ultra-sensitive heterodyne receivers for use in radio astronomy is well established. In attempting to exploit the last main submillimetre atmospheric window we are developing a Pb-alloy SIS mixer to work in the frequency band 800-900 GHz. In this paper we address some of the problems with working at frequencies above the energy gap of a superconducting alloy. We also present initial results obtained from Pb-alloy SIS junctions fabricated at the University of Kent at Canterbury (UKC).
