Abstract :
An HTS (high-temperature superconductor) phase shifter with a single-SQUID (superconducting quantum interference device) device has been developed and tested at 10 GHz. Circuit parameters have been determined, and the performance has been modeled. A lumped-element equivalent circuit for the phase shifter is presented, and a qualitative fit to the measured data is provided. It is noted that this phase shifter is the first step toward a multiple device circuit with broadband true-time delay phase-shifter performance.<>
