description: As part of this graduation work, a new design of a frequency synthesizer was developed, which is necessary for the functioning of a microwave signal generation system in a quantum frequency standard. Modernization of the standard on rubidium atoms is an important and urgent task due to the fact that the main field of application of these devices is modern navigation systems. The modeling of the operation of the main functional catches of the frequency synthesizer, the development and tuning of the prototype, the study of its characteristics of the output signal characteristics were carried out. According to the results, it was found that the use of a new synthesizer design improves the instability of the frequency of the output signal of the quantum standard.
