Claims

[Scope of utility model registration request]

In a waveguide type latching circulator, in which a ferrite and an excitation coil for DC magnetizing the ferrite are arranged at a symmetrical center position in a branch waveguide branched in a point-symmetrical manner, the ferrite is arranged near or in contact with the ferrite. A waveguide type latching circulator characterized in that a resistive film is disposed parallel to the wide surface of the waveguide at or near the heightwise center of the narrow surface of the waveguide.
