More Information
Summary:The present invention discloses a single-layer cross-coupling filter comprising a cavity, a resonant structure and a partition wall, the resonant structure is integrally formed and installed in the cavity, the resonant structure includes at least two rows of resonant units distributed along a signal transmission path and located in a same plane of the receiving space, each row resonant unit further including a plurality of resonators; the partition wall is arranged between two rows of the adjacent resonant units, and on which a coupling window is formed, the cross coupling between the two adjacent resonators in different rows is formed through the corresponding coupling window. The present invention realizes the smaller size of the filter, and at the same time reduces the processing and assembly costs, and the processing and assembly tolerances.
