摘　　要：介绍了一种用于铷原子频标的小型化物理系统。该物理系统采用了开槽管式微波腔和分离滤光设计方案，体积为30cm^3。对该物理系统进行了初步测试，短期频率稳定度为3．8×10^-12／r^1/2，表明该物理系统同时具备了小型化和高信噪比特点，可以应用于高性能小型化铷原子频标。A miniaturized physics package for rubidium atomic frequency standards is described. In the design a slotted tube cavity with small size and the separated filter technique （SFr） were used. The whole package is of 30 cm^3 in volume. A preliminary test on the physics package was carried out, and a short term frequency stability of 3. 8×10^-12/r^1/2 was obtained. The physics package has small size and high signal to noise ratio simultaneously, and can be used as a high performance miniaturized rubidium atomic frequency standards.
