Abstract
A new method for generation of the output signal of a frequency synthesizer of quantum frequency standards is considered. It is demonstrated that this method provides an opportunity to enhance spectral characteristics of the output signal, expand the range of output frequencies, and reduce the tuning step of the output frequency. A considerable (more than 10%) improvement in the frequency stability of a cesium-133 quantum standard and a 2.4-fold improvement in its temperature coefficient of frequency are reported.
