Abstract :
A dual-frequency unequal power divider design optimization with genetic algorithm is proposed. The structure of power divider is composed of two-section transmission line transformers and two isolated resistors. In the genetic algorithm, elitist strategy, crossover and mutation of changing probability are preserved to prevent premature convergence. The optimized parameters of power divider could be got rapidly and efficiently. The performance of the power divider is analyzed with software ADS. The simulation results show that impedance is matching at all ports and isolation meets the application requirements.
