摘要

本文提出了一种新颖的虹膜耦合腔滤波器谐振腔结构，该结构在谐振腔顶部增加一个锥形块。采用基于模型的灵敏度分析方法研究了锥块的物理性质对谐振腔内电场的影响。通过优化锥角，可以在降低电场强度的同时显著提高功率处理能力。此外，还提出了用于大功率射频滤波器的单腔谐振器的设计方法。将该结构应用于eNodeB的空腔滤波器设计，将功率处理能力从148.9W提高到449.4W。

A Novel Resonator Structure to Improve Power Handling Capacity in Iris Coupled Cavity Filter

In this paper, a novel structure of resonator in iris coupled cavity filter is proposed, in which a cone block is added to the top of resonator. A model-based sensitivity analysis is made to investigate the impact of physical properties of cone block to electrical field in the resonator. By optimizing the cone angle, electrical field strength can be reduced while power handling capacity can be improved significantly. Moreover, a procedure for designation of single cavity resonator used in high power RF filter is also sketched. This proposed structure is applied to design a cavity filter for eNodeB, which improves the power handling capacity from 148.9W up to 449.4W.
