Opportunity of solid-state oscillator stabilization by shielded dielectric resonator

Abstract

The possibility of the frequency stabilizing of mm-wave oscillator by external high-Q shielded dielectric resonator through their electromagnetic coupling at using the planar waveguide is considered. It is shown that the phase synchronization of the waves emitted by the oscillator and the own whispering gallery modes of shielded resonator is achieved by changing the position of the output slot of the oscillator in a planar waveguide. Thus, oscillator frequency stabilization by the external high-Q resonator is achieved on a “to pass” scheme. The high efficiency coupling between shielded resonator and planar waveguide is shown.
