摘　　要：文章给出了带传输零点的广义切比雪夫滤波器的分析方法,介绍了优化算法,并讨论了其在滤波器综合设计中的应用,得到耦合矩阵的实际形式。然后对实际微波滤波器的调试技术进行了研究,提出一套人工快速调试方法。最后利用仿真软件建立一个八阶同轴腔滤波器模型并加工调试,实际测试与理论结果吻合较好。A method for analyzing Chebyshev filters with transmission zeroes is represented. Optimization is introduced to get the final practical coupling matrix. Then through the research on tuning technique for microwave filters, a manual fast tuning method is presented, Finally, an eight-pole coaxial filter which is modeled in software is fabricated and tuned, The simulation result agrees very well with the theoretical one.
