Abstract
A microwave filter has first and second subfilters. Each subfilter has at least one single mode resonator and a preset electrical response. The second subfilter is cascaded to the first subfilter by coupling one of the at least one single mode resonator of the first subfilter to one of the at least one single mode resonator of the second subfilter. The microwave filter has an overall transfer function dependent upon the selection of the first and second subfilters from a plurality of subfilters having different preset electrical responses.
