  • Publication number: 20240177905
    Abstract: A gapless ferrite structure for circulator or isolator includes a first base having a first flange and a first limit slot surrounded by the first flange, a second base having a second flange and a second limit slot surrounded by the second flange, a ferrite with two ends accommodated in the first limit slot and the second limit slot respectively, two limit magnets installed on the first base and the second base respectively and configured to be corresponsive to the ferrite to generate an attraction force on the ferrite, and two sealing units configured between an end of the ferrite and the first limit slot and between the other end of the ferrite and the second limit slot respectively. In this way, a gapless structure can be formed on a signal transmission path in a circulator or isolator.

  • Publication number: 20240178536
    Abstract: 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.
