Document Type and Number:
Japanese Patent JP4656180
Kind Code:
B2
Abstract:
A nonreciprocal circuit device includes a ferrite-magnet element having ferrite provided with first and second central electrodes intersecting each other in an insulated manner and two permanent magnets arranged to sandwich the ferrite to apply a DC magnetic field thereto, a substrate on which the ferrite-magnet element and matching circuit elements are mounted, and a flat plate yoke. A first resin layer made of a cured liquid resin is provided at bonding portions of the ferrite-magnet element to the substrate, and a second resin layer made of a cured soft sheet-shaped resin adhered to a rear surface of the flat plate yoke is provided around the ferrite-magnet element and the matching circuit elements.
