Abstract
The utility model discloses a rectangular dual-mode resonant cavity. The rectangular dual-mode resonant cavity includes an input-output structure, a rectangular dual-mode resonant cavity, and a coupling structure between adjacent rectangular dual-mode resonant cavities. The input-output structure is arranged at The rectangular dual-mode filter is connected to the rectangular dual-mode resonant cavity at both ends of the rectangular dual-mode filter, and is connected to the rectangular dual-mode resonant cavity through a coupling structure. Part or fall into part. The protruding part or the recessed part can have any shape, and multiple protruding parts or recessed parts can be provided on the same rectangular dual-mode resonant cavity. Through the arrangement of the protruding part or the recessed part, the design of the position, size and length of the coupling structure between the resonant cavities can be made more flexible. The utility model belongs to a filter technology, which is mainly used in electronic systems of various microwave bands, especially in the fields of radar, communication, missile guidance and the like.
