Non-Reciprocal Superconducting Microwave Devices

Authors: Erwin Belohoubek; Alberto Pique; Steven Green; Venky Venkatesan; NEOCERA INC COLLEGE PARK MD
 
Abstract: One of the major issues revolving around high temperature superconducting (HTS) microwave technology is that, while researchers have applied it to components of various systems, far fewer integrated systems have been designed; such integrated designs are essential for HTS technology to be successfully implemented for practical applications. A variety of HTS microwave components (such as filters and delay lines) have been demonstrated that perform better, weigh less, and occupy less space than state-of- the-art non- superconducting components; however, practical microwave systems also require compatible non-reciprocal devices (such as circulators and isolators) to reduce performance-limiting interactions between the individual components. By applying HTS technology to these non-reciprocal components and integrating them into a system, a complete HTS integrated microwave circuit can be produced.
