ABSTRACT:
A compact superconducting filter device can easily change a bandwidth and a center frequency without changing a pattern or shape of the filter. A filter pattern is formed on a substrate made of a dielectric material. The filter pattern is made of a superconductor material. A signal input line and a signal output line are formed on the substrate so as to extend from a periphery of the filter pattern. An adjust plate is located above the filter pattern with a predetermined distance therebetween. The adjust plate is formed of one of an electrically conductive material, a superconductive material and a dielectric material.
