| Abstract: | Results on three types of passive microwave devices fabricated and tested using epitaxial thin films of Tl2CaBa2Cu 2O8 grown on LaAlO3 are reported. A microstrip ring resonator with unloaded Q of 2740 at 77 K and 33 GHz is described. A superconducting 4.6 GHz band-reject filter with unloaded Q greater than 15000 when operated at 77 K is reported. In addition, results on a multiple microstrip bandpass filter are presented |
