Abstract :
Outlines two possible trends in the field of ultra-low noise microwave oscillators. First, it has been shown that applying principles of interferometric signal processing enables the design of microwave oscillators, which combine excellent phase and amplitude noise performance. Secondly, the means of improving the medium term frequency stability of microwave oscillators have been investigated. It was shown that the frequency stability of a dual mode microwave oscillator can be significantly better than that of a flywheel quartz oscillator which is used for the phase locking of its two spectral components
