Abstract :
The operation of a low phase noise 10.35 GHz microwave cryogenic sapphire resonator oscillator is demonstrated. Based on a very simple architecture, the oscillator presents phase noise performances of -104 dBrad2/Hz at f=10 Hz off the carrier (slope 1/f 3), lower than -152 dBrad2/Hz at f=1 kHz (slope 1/f), and of -160 dBrad2/Hz at fgsim10 kHz (white)
