AN Q-ENHANCED HYDROGEN MASER WITH A STABLE Q AND A STABLE FEEDBACK PHASE

Briefly introduction to the theory of the compact hydrogen maser and the Q-enhanced hydrogen maser,and a positive feedback circuit design of the Q-enhanced hydrogen maser with a stable Q and a stable feedback phase is described,and then give the design scheme and tested data which show the design is feasible. At last,give a new design scheme with the DSP as the core of the whole system.
