Claims

[Scope of utility model registration request]

A 3dB power divider, two phase shifters for changing the phase of the two radio waves distributed by this 3dB power divider, and a 3dB directivity for combining the two radio waves that have passed through these phase shifters. In a variable power divider configured with a coupler, the above 3 dB
The power divider is composed of a conductor plate and a radio wave absorber plate provided in a plane perpendicular to the direction of the electric field in the waveguide, and the phase shifter is composed of two waveguide-type ferrimagnetic phase shifters. A variable phase shifter stacked in the direction of the electric field and two waveguides as a 3 dB directional coupler are stacked in the direction of the electric field, and a plurality of common walls of these two waveguides perpendicular to the electric field are used. A variable power divider characterized in that it is constructed using 3 dB directional couplers connected by waveguides.
