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.

The present disclosure discloses a high-temperature resistant and small-diameter optical cable and a preparation method thereof. The high-temperature resistant and small-diameter optical cable is prepared by using acrylate as a coating material, using PHB/PET liquid crystal copolyester as an outer protective layer material and using an extrusion process. Compared to traditional optical cables, the novel optical cable has advantages in small diameter, low loss attenuation, good microbending property, excellent mechanical property, long one-time finished length (10 km&#x2dc;26 km), long storage time, simple preparation process and wide operating temperature range.
