Abstract :
The mathematical analysis of a hybrid method of frequency synthesis is carried out, allowing theoretically to estimate level of noise components. Power spectral densities of a phase noise of an output signal of a hybrid synthesizer of frequencies are calculated. Comparison of level of the noise components received experimentally and theoretical is made.
