Patent number: 12113262Abstract: A cross-coupling structure for dielectric cavity filters includes a base and a tuner. The base is communicated with plural resonant cavities, a side through hole and a blind hole, and has a first channel formed between two adjacent resonant cavities which are not used for producing cross-coupling, and a second channel the resonant cavities formed between two adjacent resonant cavities which are used for producing cross-coupling. The side through hole is penetrated through the base and communicated with the second channel. The blind hole is formed on a wall of the second channel and has an opening facing the side through hole. The tuner is entered into the second channel from the side through hole and extended into the blind hole and can be adjustably moved between the opening of the blind hole and the bottom of the blind hole to set a cross-coupling amount target value.Type: GrantFiled: November 30, 2022Date of Patent: October 8, 2024Assignee: UNIVERSAL MICROWAVE TECHNOLOGY, INC.Inventors: Tung-Yi Wu, Sheng-Feng Yeh, Wun-Kai Wu, Sung-Fan Liu, Chien-Chih Lee, Jen-Ti Peng
