An example of design of the one-ring microwave a synthesizer on the basis of a direct digital synthesis (DDS) and system of a phase auto-adjust of the frequency (PLL) as a frequency multiplier is reviewed. Phase noise at the output of a digital synthesizer (100 MHz) and a frequency multiplier output on PLL (8 GHz) depending on noise characteristics of separate elements of the scheme of construction are investigated.
