Nonreciprocal ciruit device and communication device using same

摘要

A nonreciprocal circuit device it provided which has an improved reflection characteristic of the port of the center conductor which is disposed orthogonally to the side-walls of a yoke. In this nonreciprocal circuit device, the conductor width of one center conductor which is disposed orthogonally to the side-walls of the yoke is made wider than that of each of the two other center conductors.
