High-Q Tunable Microwave Superconducting Strip-Line Filters

Abstract

The objective of the Phase II SBIR project was to develop high Q, tunable microwave filters by using a cryogenic piezoelectric actuator to mechanically tune a high temperature superconducting (HTS) resonator. The concept, designated piezotun-HTS, will enable a broad range of civilian and military applications that require precise band selectivity over a broad frequency range. In Phase I of this project, a 25% frequency tuning range was successfully demonstrated between 2 and 8 GHz by using a piezoelectric bending element to adjust the width of an air gap between a microstrip resonator and a dielectric or metal tuning plate. In Phase II, the piezotune-HTS and strip-line resonator concepts are applied to achieve large tuning range and low insertion loss.
