Waveguide ferrite phase shifter

The authors of the article present results of Reggia–Spencer phase shifter modification. They list the most important parameters of the device to be optimized. These are: support of a given operating band when exposed to a range of temperature; stabilization the phase performance within the operating band; maximization of the quality factor; minimization of phase setup errors; achievement of given phase shifter speed and low power consumption. As a result of experiments with sizes and materials, the modified device received sub-square waveguide, ferrite-dielectric core and titanium housing with silver coating. All these changes let the phase shifter become the lightest and the most miniature among devices of this type.
