| Abstract: | An ultra-miniature Rb atomic clock is reported in this paper. For this Rb atomic clock, the microwave cavity is filled with a new type of ceramic material to reduce the physics package, the Rb spectrum lamp can lighten instantly with the aid of a voltage step-up circuit. Besides, it is the first time in China for this kind of clocks that the low voltage technique is applied to the circuits to realize 12 V (DC) supply and the output signal of this ultra-miniature Rb atomic clock can be synchronized with outside 1 PPS (1 pulse per second) signal. The volume of this Rb atomic clock is 190 mL and it can be locked in 3 minutes after starting. The frequency stability of this clock is 1.5×10~(-11)/(√τ)(τ:1～1 000 s), the power dissipation is 5.5 W for stable status. |
