Annotations languages:

The variants of practical application of combined synthesizers on the integrated chips are considered. The expressions for phase noises power spectral density model of combined synthesizers on the basis of phase lock system with DDS feedback circuit are given. The simulation results of noise characteristics such synthesizers for a number of output signals are displayed.
Keywords: combined synthesizers, phase lock, noise characteristics
