New Temperature Compensated Sapphire-Rutile Resonator Oscillator

Abstract

The paper presents the characterization of a new microwave temperature compensated sapphire-rutile resonator oscillator. The oscillator frequency instability performances are better than 2 times 10-13 for tau < 1000s, and the frequency drift is estimated at 2.5 times10-12/day. These medium and long term results constitute, up to now, the state of the art for microwave temperature compensated sapphire resonator oscillator
