Dielectric waveguide power limiter

摘要

A dielectric waveguide power limiter for a self-oscillating mixer operating on millimeter-wave frequencies. The limiter includes a high resistivity silicon dielectric waveguide and a Gunn oscillator. A plurality of dielectric resonators each including a high uniaxial anisotropy ferrite sphere embedded therein are positioned between the power input end of the waveguide and the Gunn oscillator.
