摘要:

针对滤波器设计后期三维全波仿真优化耗时长和结果不容易收敛的问题,提出了一种基于模型校正技术的滤波器设计方法,该方法通过预先得到的拟合参数对滤波器结构尺寸进行迭代校正,避免了耗时的全波仿真优化。并通过一个4腔的同轴腔体滤波器的设计实例验证了文中方法。滤波器的电磁仿真结果与理论综合结果吻合良好,证实了该方法的有效性。

关键词: 模型校正, 电磁仿真, 耦合系数, 腔体滤波器

Abstract:

The paper presents a novel filter design method based on model correction technology to handle the time consuming full wave simulation of the filter.By pre-approved fitting formula,the iterative correction is carried out on the filter structure size,avoiding the time-consuming full-wave simulation optimization.A design example of a 4 coaxial cavity filter is provided.Simulation results are in good agreement with the theory of electromagnetic filter synthesis results,confirming the validity of the proposed method.

Key words: model correction;electromagnetic simulation;coupling coefficient;cavity filter
