A circulator includes connecting arms designed in accordance with the MIC technique which merged to form a branch, wherein a disc constructed of gyromagnetic material is arranged in the branching zone and is subjected to a constant magnetic field produced by a permanent magnet. The disc is surrounded by a plate constructed of dielectric material. On one side of the plate the connecting arms for the branch are provided and on the other side of the plate a continuous metallization is applied. An insert consisting of dielectric material is disposed between the line branch and the disc of gyromagnetic material, the dielectric constant of the insert being smaller than the dielectric constant of the gyromagnetic material. |
