Patent number: 11984635Abstract: A filter includes a filter frame and at least two resonators. A receiving space is formed in the filter frame. The at least two resonators are disposed in the receiving space and distributed along a signal transmission path. Adjacent resonators on the signal transmission path are coupled. Each resonator includes a body part and a bending part. One end of the body part is grounded. The bending part includes a head bending part and an end bending part, the head bending part being connected to the end bending part to form a resonator structure circulating in a counterclockwise or clockwise direction.Type: GrantFiled: July 16, 2021Date of Patent: May 14, 2024Assignees: PROSE TECHNOLOGIES (SUZHOU) CO., LTD., PROSE TECHNOLOGIES LLCInventors: Dunrong Li, Renhu Luo, Ze Yin, Jian Lu

Patent number: 11973255Abstract: 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.Type: GrantFiled: February 7, 2022Date of Patent: April 30, 2024Assignees: PROSE TECHNOLOGIES (SUZHOU) CO., LTD., PROSE TECHNOLOGIES LLCInventors: Dunrong Li, Renhu Luo, Ze Yin, Qiang Li

Patent number: 11923588Abstract: A single-layer cross-coupling filter includes a cavity in which a receiving space is formed; an integrally formed resonant structure installed in the receiving space; and at least one partition wall. The resonant structure includes at least two rows of resonant units distributed along a signal transmission path. The at least two rows of resonant units are located in a same plane of the receiving space, and each row of the resonant units includes a plurality of resonators. The resonators on a same row are coupled and connected to form signal transmission, and at least two adjacent resonators in different rows are coupled and connected to realize cross-coupling.Type: GrantFiled: July 16, 2021Date of Patent: March 5, 2024Assignees: PROSE TECHNOLOGIES (SUZHOU) CO., LTD., PROSE TECHNOLOGIES LLCInventors: Dunrong Li, Renhu Luo, Ze Yin, Jian Lu

Patent number: 11799181Abstract: 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.Type: GrantFiled: November 10, 2021Date of Patent: October 24, 2023Assignees: PROSE TECHNOLOGIES (SUZHOU) CO., LTD, PROSE TECHNOLOGIES LLCInventors: Dunrong Li, Renhu Luo, Ze Yin, Qiang Li
