Abstract: The invention relates to a single mode multi-cavity microwave filter that includes a housing formed with a plurality of walls which define at least two rows of side-by-side dielectric loaded cavities, wherein sequential cavities are coupled to one another via slots or probes in the walls therebetween and at least one pair of non-sequential adjacent cavities are coupled via a slot or probe. The coupling via the slots is defined mathematically as positive coupling. The probe is selectively configurable to provide positive or negative coupling relative to the sign of the slot coupling. Further, at least one non-adjacent, non-sequential pair of cavities is coupled via a second probe that may be configured to provide either positive or negative coupling relative to the sign of the slot coupling. The filter housing supports a plurality of adjustable fins which extend into the slots, one fin to each slot, to selectively adjust the size of the slot.

Abstract translation: 本发明涉及单模多腔微波过滤器，其包括形成有多个壁的壳体，所述多个壁限定了至少两排并排介质负载腔，其中顺序腔通过狭槽或探针彼此耦合 在其间的壁中，并且至少一对非顺序相邻的空腔经由槽或探针耦合。 通过槽的耦合在数学上定义为正耦合。 探针可选择性地配置为提供相对于槽耦合的符号的正或负耦合。 此外，至少一个不相邻的非顺序的空腔对经由第二探针耦合，第二探针可以被配置为相对于狭槽耦合的符号提供正或负耦合。 过滤器壳体支撑多个可调节的翅片，其延伸到槽中，一个翅片延伸到每个槽，以选择性地调节槽的尺寸。
