Abstract :
Power stabilized microwave oscillators of exceptional short term stability have been realized from cryogenic sapphire resonators with loaded Q-factors of 10/sup 9/ at X-band and 6 K. These oscillators have exhibited a fractional frequency stability of 3-4/spl times/10/sup -15/ for integration times from 0.3 to 100 seconds degrading to 10/sup -14/ at 1000 seconds.<>
