| Abstract: | Based on the basic principle of multiple cavity RF filter, a tunign structure which is composed of new condenser armature was introduced. A method to design multiple cavity tunable filters was presented. With an advanced 3D electromagnetic field simulator, the parameters of the filter were analyzed and optimized. The result shows that the performance of the filter keeps stable in the process of tuning. |
