Abstract

In this paper, we present results for a high-Q frequency-temperature compensated dielectric resonator in the framework of the PHARAO project. This design and this analysis of performance are based on a two dimensional finite element method (FEM), with a good agreement between theory and experiment. This study shows that a good isolation between the whispering gallery mode and spurious mode is necessary to obtain good performances. A compensation temperature of 71.8 K for a high quality factor of 10.7 millions is measured. This device is generally used in oscillator applications, but in the filter domain, high-Q frequency-temperature compensated dielectric resonator can be interesting.
