Fabrication process,structure and its effect on parameters of low temperature co-fired chip ceramic microwave resonators were presented.

Fabrication process, structure and its effect on parameters of chip multilayer ceramic microwave resonators were presented.

A practical method of measuring microwave resonator unloaded Q-factor is presented,which could eliminate phase shift of feed line when Q-factor is estimated by critical-points method.

The analysis and design for the microwave cavity in laser-cooled Rb fountain clock developed by ourselves were presented and the basic parameters of the microwave cavity developed were designed in this paper.

According to the modulation of mi-crowave cavity on different input signals,this paper judges the relationship between the frequency of input signal and the reso-nant frequency of microwave cavity through amplitude discrimination and phase demodulation,then,we use MCU to control the output frequency of VCO to .

When using a microwave resonator for steam wetness measurements,deposited liquid droplets form a water film on the resonance cavity s inner surface.

The resonator plays a role of wetness sensor in the process of steam wetness measuring based on microwave resonator perturbation.

Start with the choice of resonance model,introduces the practical process of structure design of microwave resonator in details.

The error of atmospheric structure explore equipments in common is bigger,based on the change principle of the resonance frequency of microwave resonant cavity when the medium enters into it is different,digital tester about atmosphere duct is designed.
