The radio frequency ferrite system for modulating, phase shifting, or attenuating radio frequency energy has a resonator, a ferrite polarizer, and coupling devices. The coupling devices are used to couple radio frequency signals to and from an interior of the resonator. The ferrite polarizer generates magnetic fields corresponding to an applied voltage or current. To produce phase modulation the ferrite polarizer may be used to detune the cavity from resonance by changing the orientation of the radio frequency signal with respect to a protrusion in the resonator. The ferrite system may be used for phase modulation, switching radio frequency signals, and amplitude modulation by arranging the coupling devices in various orientations and by simultaneously changing the polarization of radio frequency signals with the ferrite polarizer. Another aspect of the ferrite system, uses a waveguide, a ferrite polarizer, coupling devices, and a combiner for phase shifting, phase shift keying modulation, or phase modulation.
