Abstract
The performance of 7.3-GHz two-pole bandpass filters (5% bandwidth) fa bricated on double-sided Y-Ba-Cu-0 and Tl-Ba-Ca-Cu-0 thin films deposi ted on LaAlO3 is discussed. At 77 K, the Tl-Ba-Ca-Cu-O and Y-Ba-Cu-0 s uperconducting filters exhibited minimum passband insertion losses of 0.3 and 1.2 dB, respectively. An insertion loss of 3.4 dB was measured for an all-gold filter at 77 K. (C) 1993 John Wiley & Sons. Inc.
