中文摘要：

相干布局（CPT）原子钟被广泛的应用于通信、导航、电力以及数据传输等各个领域,对国民经济的发展起着举足轻重的作用,因此微型CPT原子钟的研制有着重大的意义。这里针对目前微型CPT原子钟对微波信号源的要求,采用锁相环倍频技术设计了一种中心频率为3.417340GHz的微波信号源,该信号源可以满足Rb87微型CPT原子钟的研制,这为微型CPT原子钟的实现奠定了坚实的基础。

英文摘要：

Coherent Population Trapping（CPT）atomic clock is widely used in communications,navigation,data transmission and other fields,and plays an important role in the development of the national economy.So the research on the miniature atomic clock is of great importance.Based on the requirement of microwave signal source by miniature CPT atomic clock,and by using Phase Lock Loop and frequency-doubling technology,a microwave signal source with a central frequency of 3.417 340 GHz is designed,which could satisfy the research of Rb87 micro-CPT atomic clock,thus laying a solid foundation for the realization of micro-CPT atomic clock.
