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: 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

Patent number: 11671293Abstract: A device for implementing an antenna Ping function includes a primary module and a secondary module. The secondary module includes a secondary controller, a multiplexer, a first On-Off Keying (OOK) modem, a second OOK modem connected to the secondary controller and a corresponding multiplexer, and a plurality of antenna radio frequency (RF) ports. The multiplexer is connected to the plurality of antenna RF ports. The primary module is connected to the secondary controller through the first OOK modem. The primary module receives a Ping command transmitted by a base station, generates a Ping message, and transmits the Ping message to the secondary controller through the first OOK modem. The secondary controller transmits the received Ping message to the second OOK modem. The second OOK modem transmits the Ping message to a corresponding antenna RF port through the multiplexer. The antenna RF port feeds back a signal to the base station.Type: GrantFiled: December 3, 2021Date of Patent: June 6, 2023Assignees: PROSE TECHNOLOGIES (SUZHOU) CO., LTD., PROSE TECHNOLOGIES LLCInventors: Jifa He, Ze Liu, Zhiqiang Li, Zhicheng Xiang, Wencai Jing
