MINIATURE SUPERCONDUCTING FILTERS

Because of the intrinsic low loss of high temperature superconductors at microwave frequencies it is possible to reduce the size of filters while still retaining excellent performance, In order to accomplish th is reduction in size new filter geometry is required, Under this theme of miniaturization a number of new and novel types of microwave filte r are discussed, this includes delay line filters, lumped element filt ers and filters based on slow wave structures, Each of the filters are constructed out of high temperature superconductors (HTS).
