Abstract
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.
