摘　　要：铷原子频标输出频率随工作环境温度变化而改变,影响其频率稳定度指标。为了降低铷原子频标的温度系数,设计了一种基于铷原子基态超精细能级跃迁的微波激励频率补偿电路。该电路在保证铷原子频标相位噪声和短期频率稳定度不受影响的条件下,具有良好的温度系数补偿效果,对于进一步提高铷原子频标的技术指标具有积极的作用。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.
