Disclosed herein is a nonreciprocal circuit element that includes a magnetic rotator, and a permanent magnet that applies a DC magnetic field to the magnetic rotator. The magnetic rotator includes a center conductor, a first ferrite core laminated on the center conductor, and a dielectric provided in a gap formed between the center conductor and the first ferrite core.

A circuit assembly includes a sealable enclosure and at least one electronic circuit element contained within the sealable enclosure. The at least one electronic circuit element includes a control circuit, a garnet, and a first polymer material applied on a surface of the control circuit and on a surface of the garnet. A second polymer material fills a remaining space defined within the enclosure, the second polymer material applied on an exposed surface of the first material.

A hybrid circulator includes an isolator and an orthomode transducer coupled to the isolator. The hybrid circulator achieves high performance in the microwave and millimeter-wave (MMW) frequency range.

A modularization of a circulator and a directional coupler used in a wireless communication system comprises: a circulator; and a signal coupler, where the signal coupler does not have directivity by itself, and directivity of the circulator module is controlled by isolation characteristics of the circulator to improve electrical characteristics of a wireless communication system and miniaturize the wireless communication system by applying the electrical characteristics in common with a circulator to modularize the wireless communication system without implementation of a circuit of a directional coupler capable of sampling high-frequency signals.

The disclosure is directed to a waveguide assembly within a non-reciprocal electronic device (e.g., a circulator). The waveguide assembly may include a ferrite member, a magnetic member, and a pole assembly. The pole assembly, in combination with at least the ferrite member and the magnetic member forms a magnetic circuit. The pole assembly has a spatial variance of a magnetic reluctance. The spatial variance of the magnetic reluctance of the pole assembly provides an increase in a uniformity of a magnetic flux throughout a volume of the ferrite member. A non-reciprocal property of the electronic device is enhanced due to the increase in the uniformity of the magnetic flux throughout the volume of the ferrite member.
