Monolithic high-T/sub c/ superconducting phase shifter at 10 GHz

摘要

A monolithic high-temperature-superconductor (HTS) phase shifter integrated into a 10-GHz microstrip line is described. This is the first demonstration of a nonresonant HTS circuit based on a distributed Josephson inductance approach. Phase shifts greater than 150 degrees in resonant structures and 20 degrees in broadband circuits were observed.
