High-Q frequency-temperature compensated sapphire/rutile resonator

摘要

Experimental results for the novel design of a composite sapphire-rutile frequency-temperature compensated resonator are presented. The frequency-temperature dependence was annulled when a specific balance of electric energy in the rutile and sapphire was reached at 56 K in a WGE/sub 9,0,0/ mode at 13.1 GHz with a Q-factor of 30 million.
