Abstract:
A nonreciprocal circuit device comprising:a plurality of central conductors overlappingly intersecting with each other and disposed on a magnetic member for receiving a DC magnetic field; and a coiled-shaped inductor connected at its ends to at least one portion section of said central conductors and to a signal input/output terminal, respectively; wherein said magnetic member has a substantially rectangular shape with four edge surfaces; a longitudinal axis of said inductor is parallel to a major surface of said magnetic member; said major surface of said magnetic member is perpendicular to a direction of said DC magnetic field; a magnetic flux produced by said inductor passes in a direction that is perpendicular to the direction of said DC magnetic field with respect to said magnetic member; and both ends of said inductor are parallel to said longitudinal axis of said inductor; and said both ends are not disposed in a straight line.
