Abstract: The output frequency of Rubidium atomic frequency standards changes with the fluctuation of environment temperature,which affects its specification of frequency stability.In order to reduce the temperature coefficient of Rubidium atomic frequency standards,a microwave excitation frequency compensation circuit is designed.Without deteriorating the phase noise and short-term frequency stability of Rubidium atomic frequency standards,the circuit has a good temperature coefficient compensation effect,which has a positive effect on further improving the technical indexes of Rubidium atomic frequency standards.
