THE STUDY OF RF OSCILLATOR CIRCIUT WITH FEEDBACK FOR RUBIDIUM SPECTRAL LAMP

The rubidium spectral lamp is one of the important parts of the rubidium atomic frequency standard（RAFS）,its stability has great influence on the performance of the RAFS.In the paper,The RF oscillator circuit,feedback control and lamp cavity of the rubidium spectral lamp were researched,new idea and approaches were expounded,and The stability test result of improved rubidium spectral lamp were given.
