Abstract
Novel back side coupling was used to produce high-power high temperatu re superconducting (HTS) filters. Several 2.88 GHz, 0.7% equal-ripple bandwidth, 2-pole TE(01) mode filters were fabricated using Tl2Ba2CaCu 2O8 HTS thin films on 2O-mil LaAlO3 substrates. The calibrated, measur ed performance of the filter at 77 K was <0.1 dB in-band insertion los s and 0.2 dB ripple up to 8 W. The uncalibrated measured performance o f the filter was unchanged up to 21 W. This represents a significant a dvance in the power handling of planar HTS filters. These high-power, high-performance, compact HTS filters were designed to be used in tran smitters for satellite communications.
