A low phase noise oscillator prototype at 10GHz using Sapphire cavity for the Brazilian gravitational wave detector Mario Schenberg

This work describes the development of an oscillator prototype at 10GHz that consists of a feedback loop amplifier using a Sapphire loaded cavity and a tunable cylindrical cavity filter. Measurement procedures involving a phase detector circuit technique are described. The phase noise performance obtained at room temperature is -127,32 dBc/Hz at 3KHz and the electrical quality factor (Q) is around 105.
