Recommendations for the Drift Thermal Compensation of the Oscillator Frequency Using a Dielectric Resonator

This paper presents recommendations for reducing the frequency temperature shifts in oscillators formed by an active structure that forms a source of microwave oscillations, which is controlled by the high-quality open dielectric resonator in the feedback loop. The advantages and disadvantages of various options for implementation of temperature compensators for frequency shifts on the example of the frequency band 8–12 GHz transistor oscillator with dielectric resonator are considered and evaluated.
