Abstract
There are provided a gyromagnetic component and a non-reciprocal circuit device having excellent high-frequency characteristics. A ferrite substrate 12 and a center electrode 11 are included. At least a part of the ferrite substrate 12 is covered with an insulating film 114. A second central conductor 112 constituting the center electrode 11 is caused to adhere to a surface of an insulating film 12. A non-reciprocal circuit device is configured to incorporate this gyromagnetic component therein.
Claims2
A gyromagnetic component for a non-reciprocal circuit device, the gyromagnetic component comprising:
- a ferrite substrate;
- and a center electrode,
- wherein at least a part of the ferrite substrate is covered with an insulating film, and
- at least a part of the center electrode is caused to adhere to a surface of the insulating film.
A non-reciprocal circuit device comprising:
- a gyromagnetic component;
- a permanent magnet;
- and a yoke,
- wherein the gyromagnetic component comprises an ferrite substrate and a center electrode,
- at least a part of the ferrite substrate is covered with an insulating film, and
- at least a part of the center electrode is caused to adhere to a surface of the insulating film,
- the permanent magnet is provided on at least one surface side of the gyromagnetic component and applies a direct-current magnetic field to the gyromagnetic component, and
- the yoke constitutes a magnetic path for a magnetic field generated by the permanent magnet.
