摘　　要：为满足对小型化铷原子频标的需求,设计了一种超小型汽泡铷原子频率标准。介绍了该超小型汽泡铷原子频标的设计。通过全新设计的小型光谱灯和集成腔泡系统,配合优化设计的电路部分,成功地将整机体积减小至140 cm3,重量仅为250 g,稳态功耗7 W。测试结果表明其短期稳定度优于1.5×10-11/τ(1 s≤τ≤100 s)。In order to meet the requirements to miniature rubidium frequency standard,an ultra-miniature rubidium vapor cell frequency standard has been designed.The design of this ultra-miniature rubidium vapor cell frequency standard is introduced in this paper.With the new-designed miniature lamp,integrated filter technique（IFT） and optimized electronic circuits,the volume of this frequency standard is successfully downsized to 140 cm3,and the weight is 250 g.In steady state,the power dissipation is only 7 W,and the short-term stability is superior to 1.5×10-11/（1 s≤ ≤100 s）.
