摘要
介绍了粒子群优化算法的基本原理,并讨论了其在带传输零点的广义Chebyshev微波滤波器设计中的应用,得到了耦合矩阵的实际形式。利用耦合相位关系模型分析出附加耦合的极性,以决定零点的分布。最后利用仿真软件建立了一个八阶同轴腔基站滤波器模型并加工生产,实际测试与理论结果吻合较好。
After a brief introduction to the Particle Swarm Optimization（PSO） algorithm,generalized Chebyshev microwave filters with transmission zeroes for base-station application is analyzed and optimized with PSO to obtain the final practical coupling matrix.The polarity of appendix coupling in the filter is further analyzed by using a phase relation model.Finally,an eight-pole coaxial SCDMA base-station filter is designed,fabricated and measured.The simulation result and the measurement coincide very well.
