Design of Dual-Frequency Wilkinson Power Divider with Genetic Algorithm

摘要：

The Genetic Algorithm with the elitist strategy isapplied for the design of Dual-Frequency equal-splittingWilkinson Power Divider.It is composed of a two-sectiontransmission line transformer and two isolation resisters.Aftereven and odd mode analysis with ideal transmission-line model,the optimal parameters are obtained by Genetic Algorithm,crossover and mutation of changing probability are used toprevent premature and rapid convergence in Genetic Algorithm,so as to get the optimized results rapidly and efficiently.Theperformance of the Power Divider is also simulated with ADS.The result shows that impedance is matched at all ports andisolation between the two output ports is more than 40dB.Thismethod can be used to practical design.
