Abstract
A 9.72 GHz avalanche transit time oscillator (ATTO) with FM noise of 100 Hz rms/100 Hz was synchronized by a 9.72 GHz stabilized klystron with FM noise of 0.01 Hz rms/100 Hz. The FM noise of the synchronized oscillator was reduced, but not as much as expected for modulation frequencies below 10 kHz. The AM noise was not changed by synchronization.Keywords
