Abstract

PURPOSE:To perform broad band, by using the material high in permeability as the impedance converter. CONSTITUTION:The input high frequency power from one port is appeared at either of adjacent ports depending on the direction of the DC magnetic field determined with the permanent magnets 3, 3' provided external the waveguide 1 through the difference of the positive and negative rotary permeability of the ferrite 2. The dielectric substances 4, 4' are placed up and down the ferrite 2 and they are inserted in the waveguide 1 together with the impedance converter 6. Further, the converter 6 consists of high permeability material, the DC magnetic field formed with the magnets 3, 3' is concentrated to the ferrite 2, increasing the magnetic field of the ferrite 2. As a result, Q at the branch point of the tube 1 is lowered and broad band can be obtained.
