Abstract
A nonreciprocal circuit device is provided which has an improved reflection characteristic of the port of the center conductor which is disposed parallel with one side of a magnetic body. In this nonreciprocal circuit device, a magnetic assembly is formed by disposing three center conductors on a magnetic body having a rectangular parallelepiped planar shape. The conductor width of one center conductor which is disposed parallel with one side of the magnetic body is made wider than that of each of the two other center conductors.
Claims5
A nonreciprocal circuit device comprising:
- a magnetic body having a rectangular parallelepiped shape, said magnetic body including three center conductors arranged to intersect one another at a predetermined angle, provided in an electrically insulated state from one another, and one of which is disposed substantially parallel with one side of the magnetic body,
- wherein the conductor width of the center conductor which is disposed substantially parallel with one side of the magnetic body, is set to be wider than the conductor width of each of the two other center conductors.
