Abstract
This paper proposed a new circuitry to make frequency modulation (FM) microwave signal for coherent population trapping (CPT) atomic clock application. This circuitry employed one phase lock loop (PLL) chip and one direct digital synthesis (DDS) chip to complete the FM for the microwave signal used in CPT atomic clock. The FM frequency and depth could be controlled by DDS. Test results showed this circuitry could well make the FM signal for CPT atomic application.
