MICROWAVE FILTER HAVING CASCADED SUBFILTERS WITH PRESET ELECTRICAL RESPONSES |
摘要 |
A microwave filter (10) has first and second subfilters (18a-b). Each subfilter (18a-b) has at least one single mode resonator (12a-g) and a preset electrical response. The second subfilter (18b) is cascaded to the first subfilter (18a) by coupling one of the at least one single mode resonator (12a-c) of the first subfilter (18a) to one of the at least one single mode resonator (12d-g) of the second subfilter (18b). The microwave filter (10) has an overall transfer function dependent upon the selection of the first and second subfilters (I8a-b) from a plurality of subfilters having different preset electrical responses.
