A cross-coupled filter includes a minimum resonant structure including four resonators. In the minimum resonant structure, two resonators in the same row form a group, and two resonators in the same row are capacitively mainly coupled or inductively mainly coupled; two resonators in the same column are electrically and magnetically hybrid coupled; and the coupling polarities of the two groups of resonators in the two rows of resonant units are opposite to each other and form at least a cross-coupling. The invention realizes miniaturization and light weight in structural characteristics, and realizes low loss and good harmonic characteristics in electrical performance.

Cross-coupled filter

A cross-coupled filter includes a resonant structure including a plurality of columns of resonant units, each column of resonant units includes at least two resonators. A dominant coupling mode of a coupling between two adjacent resonators in a same column is electrical coupling or magnetic coupling. Dominant coupling modes of a plurality of groups of two adjacent resonators in the same column alternate between electrical coupling and magnetic coupling. A dominant coupling mode of a coupling between two adjacent resonators in adjacent columns is electrical coupling or magnetic coupling. Dominant coupling modes of a plurality of groups of two resonators of two adjacent columns alternate between electrical coupling and magnetic coupling, to form at least a set of cross-coupling. The present disclosure realizes miniaturization and light weight in structural characteristics, and realizes low loss and good harmonic characteristics in electrical performance.
