About the microwave excitation signal formation in the quantum frequency standard on cesium atoms – 133

Abstract The features of microwave excitation signal formation in the quantum frequency standard on cesium atoms - 133 were determined. To improve the characteristics of microwave excitation signal, a new method for its formation has been proposed taking into account the features we have identified. Studies have shown that the use of this method allow to improving the spectral characteristics and reducing the step of tuning of microwave excitation signal. The obtained experimental results allowed establishing that the use of this method improves the stability of the output signal of the quantum frequency standard on 20%. The features we have identified allow us to expand the possibilities of research aimed at developing new methods and techniques for improving the characteristics of the microwave excitation signal and characteristics of quantum frequency standard output signal.
