  • Patent number: 11916276
    Abstract: A circulator comprising a grounding plane including a first side and a second side, a magnet disposed on the first side of the grounding plane, a ferrite-based disk disposed on the second side of the grounding plane, and a conductor disposed on a side of the ferrite-based disk opposing the grounding plane. The conductor includes an elongate portion and the elongate portion has a distal end section projecting inwardly adjacent to a side of the magnet opposing the grounding plane. The circulator comprises a circulator housing including a plurality of side portions. The side portions have a first section and a second section, the second section extending further around a periphery of the housing than the first section such that a gap between neighboring first sections is wider than a gap between neighboring second sections.

  • Publication number: 20230102155
    Abstract: The disclosed technology relates to a ceramic composition and an article formed therefrom. A ceramic article for radio frequency applications is formed of a ceramic material having a chemical formula represented by: Bi1.0+aY2.0-a-x-2yCax+2yFe5-x-yMIVxVyO12 or Bi1.0+aY2.0-a-2yCa2yFe5-y-zVyInzO12. The ceramic material has a composition such that a normalized change in saturation magnetization (?4?Ms), defined as ?4?Ms=[(4?Ms at 20° C.)-(4?Ms at 120° C.)]/(4?Ms at 20° C.), is less than about 0.35.
