Thin film HTS passive microwave components for advanced communication systems

摘要

This paper presents results of thin film high temperature superconducting (HTS) passive microwave components recently developed for advanced communication systems, which include miniature resonators, narrow-band bandpass and bandstop filters, couplers and duplexers. The components are fabricated using YBCO thin films on either MgO or LAO substrates. Excellent performances have been achieved.
