Abstract

An RF chain having a high-frequency oscillator providing first, second and third outputs. The first output is multiplied to provide a microwave signal to an atomic beam tube; the second output is divided to provide a standard output frequency; and the third output is divided to provide a first input to a phase detector. The phase detector receives a second input from a low-frequency oscillator which is controlled by a servo signal from the atomic beam tube. The output of the phase detector provides a control signal to the high-frequency oscillator.
