Design, fabrication and testing of a microwave filter using YBCO on a YSZ buffered (100) Si substrate

摘要

We have fabricated a three-pole microstrip hairpin bandpass filter using YBa2Cu3O7 on yittrium stabilized zirconia buffered (100) silicon. The corrected pass band insertion loss of the fabricated device was 7.76 dB and it's center frequency was 2.99 GHz with a bandwidth of 35.6 MHz. An identical device fabricated using aluminum on (10 0) Silicon demonstrated no pass band response even at 10 K. An overview of the fabrication process and measurement details is presented along the results and the temperature dependence of the filter's response. (C) 2002 Elsevier Science B.V.
