摘要/Abstract

摘要：

采用遗传算法对双频等分Wilkinson功率分配器进行优化设计．双频等分Wilkinson功率分配器由两节阻抗变换器和两个隔离电阻组成．基于理想传输线模型，采用偶模/奇模分析便可得到功率分配器的参数设计方程．在此基础上，采用遗传算法进行优化设计，加入了最优保持操作、变概率的交叉和变异操作，解决了遗传算法的早熟收敛问题．使用射频仿真软件ADS对优化后的双频等分Wilkinson功率分配器进行仿真分析，结果表明:在两个给定的频率上，所有端口有着良好的匹配，隔离度大于40dB．经优化设计后的功率分配器在两个频率上都具有良好的性能．

关键词: 双频Wilkinson功率分配器, 遗传算法, 优化设计

Abstract:

The optimal design of the dual-frequency equal-split Wilkinson power divider with the genetic algorithm is proposed. The dual-frequency equal-split Wilkinson power divider is composed of a two-section transmission line transformer and two isolation resistors. Based on the ideal transmission line model, the even-odd mode technique is used to derive the design equations of parameters. Based on the above analysis, the parameters optimized with the Genetic Algorithm are discussed. In the Genetic Algorithm, elitist strategy、crossover and mutation of changing probability are preserved to prevent premature convergence. The performance of the Power Divider is analyzed by simulation with radio frequency software ADS. The result shows that impedances match well at all ports and that isolation between the two output ports is more than 40dB.Good performances of the optimized power divider at both frequencies are obtained.

Key words: dual-frequency Wilkinson power divider, genetic algorithm, optimal design
