Abstract

The invention discloses a cavity bubble system of the rubidium atom frequency standard. Integrated filtering absorption bubbles are fixed in a medium tube through heat conduction silicone grease and are arranged on one side of a microwave cavity, the direction of a microwave magnetic field is perpendicular to a coupling ring, one end of a heating tube is a full closed end, a heating power tube is fixed on the heating tube through a screw, a C field coil is wound around the medium tube, and two ends of the C field tube are fixed through insulation clamping rings. the integrated filtering absorption bubbles, the C field coil, the insulation clamping rings are placed in the microwave cavity, a microwave circuit plate covers one open end of the microwave cavity and is placed in the heating tube with the microwave cavity, one end of the coupling ring is connected with a phase step diode, and the other end of the coupling ring is connected with an external radio frequency signal wire. The phase step diode is welded on a microwave circuit board, a photoelectric cell is bonded to the microwave circuit board, and the heating power tube is fixed on the microwave cavity through a screw. The cavity bubble system is simple in structure, small in size, simple in cavity frequency micro-adjustment, high in performance index and easy to process.
