Abstract

In this paper we show that it is possible to annul the frequency - temperature coefficient of a sapphire dielectric resonator using another dielectric with the opposite frequency - temperature dependence. We have successfully annulled the frequency - temperature coefficient of a composite sapphire - strontium titanate ( - ) microwave resonator at 108 K with a resulting Q factor of 20 000 - 50 000 below 150 K.
