Abstract
The article discusses the results of modelling an ultra-low-noise reference oscillator based on a dielectric resonator with unloaded Q factor of 20,000. The design and technical characteristics of the resonator with mechanical frequency tuning from 9.85 to 10.1 GHz and electrical frequency tuning within 2.4 MHz using a varactor are given. The resonator in the entire tuning range has a loaded Q factor more than 7200. It is shown that using a low noise amplifier HMC-C072 as a part of oscillator based on a dielectric resonator and utilizing a special electrical tuning scheme, it is possible to achieve phase noise level less than −130 dBc/Hz at 10 kHz offset in the entire frequency tuning range.
