摘要

The strong electric and magnetic coupled novel HTSC (high temperature superconductor) open-loop mierostrip resonators are studied in this report and the traditional structure of open-loop resonators is improved. A miniature wide-band HTSC bandpass filter is developed by the novel structure, which is fabricated on YBCO/LaAIO3/BCO substrate with dimensions of 14.8×9.6 mm2. This filter is tested at 77K, and the specifications are that the center frequency is 2230 MHz, the bandwidth is 455 MHz, and the best insertion loss is 0.14 dB in passband.
