TL;DR: In this article, the authors present an analysis of a low-noise dielectric resonator GaAs FET oscillator in a frequency-locked loop (FLL), which is used for FM noise degeneration.

TL;DR: In this article, a frequency-agile source of microwave frequency signals is shown to include a voltage-controlled oscillator operating within a band of microwave frequencies, a crystal-controlled OO operating at a frequency lower than the band of the microwave frequencies and producing harmonics within such band.

TL;DR: An overview of frequency synthesizer techniques suitable for radar systems is presented, including key building blocks and performance limitations, and projections are made of advances in components that have a direct effect on frequency synthesis.

TL;DR: In this paper, an improved microwave frequency signal source using a single frequency offset technique which increases the frequency range of an indirect frequency synthesizer to twice the highest operating frequency of the programmable digital frequency divider in the loop includes a voltage-controlled oscillator (VCO) operating within a predetermined microwave frequency band and phase-locked to a reference oscillator operating at a reference frequency below microwave frequencies.

TL;DR: In this article, the output frequencies of a lower frequency, low noise, synthesizer are upconverted to higher microwave frequencies by mixing these frequencies with the output frequency of an ultra low noise microwave oscillator determined by a very high Q resonator.
