Abstract

We describe the design of a miniature microwave cavity for the rubidium vapor cell frequency standard with an integrated filter-absorption cell. The three-dimensional simulation and mechanical structure of a dielectric-loaded cavity operated in the TE₁₁₁ mode is also presented. As a result of this compact design, the physics package volume is reduced to 38 cm³ , and the resulting size of the whole device (3.7 cm times 7.7 cm times 7.6 cm).
