Abstract
A new configuration of the frequency synthesizer for the quantum frequency standard (QFS) on the 133Cs atoms is considered. Significant advantages of the proposed configuration in comparison with the conventional configuration are demonstrated. The frequency interval of the synthesizer is expanded and the step of frequency tuning is decreased. Spectral characteristics of the output signal of the frequency synthesizer are improved, and the frequency tuning to the neighboring resonance of the spectral line provides tuning of the QFS middle field. The metrological characteristics of the QFS with the proposed frequency standard are improved.
