  • Frequency selective limiter having an enhanced bandwidth
    Patent number: 12244048
    Abstract: Methods and apparatus for providing a frequency selective limiters (FSL) having a free-standing Yttrium Iron Garnet (YIG) film with first and second opposing surfaces. A metal plane is disposed on one surface of the YIG film to provide the YIG film with a metalized surface. At least one transducer is disposed on the other surface of the YIG film with a respective ends coupled to the metalized surface of the YIG film.
    Type: Grant

  • BROADBAND MAGNETOSTATIC SURFACE WAVE DEVICES WITH CUSTOMIZABLE FREQUENCY RESPONSE
    Publication number: 20230261354
    Abstract: Described is an intrinsically multiplexed magnetostatic surface wave (MSSW) device comprising of a pair of transducers that couple to one or more plurality of ferrite films. In embodiments, the ferrite films may be provided as one or more of a YIG, Nickle Zinc Ferrite, Lithium Ferrite configured to simultaneously provide the MSSW device having an associated plurality of MSSW operational bandwidths. The concepts, structure and technique described herein may be used to provide broadband magnetostatic surface wave devices that employ intrinsic multiplexing techniques which enable customizable frequency responses over broad bandwidths.

  • Passive thermal stabilization of self-biased junction circulators and related circuits and techniques
    Patent number: 11329357
    Abstract: Described is a self-biased circulator which includes an active layer disposed between an RF ground plane and a circulator junction circuit. The RF ground plane is disposed between the active layer and a compensating layer. The active layer and compensating layer are used in combination to reduce variation of the internal magnetic field in the circulator over temperature.
