摘要

This paper proposes an optimization design method for multi-channel broadband phase shifter with constant difference step. It analyzes the phase-shifting network parameters, and builds Particle Swarm Optimization(PSO) algorithm model. The algorithm is designed for system optimization and optimized phase shift network parameters are got. Advanced Design System(ADS) software is used to prove the stability and feasibility of the optimum design result. It shows that this method can satisfy the design specifications quickly and have a stable output of phase-shift network.%提出一种多通道宽带等差步进移相器的优化设计方法.对移相网络系统参数进行分析,建立粒子群优化算法模型,利用该算法对移相网络参数进行优化设计,得到满足设计需求的性能参数.利用先进设计系统(ADS)软件对优化设计得到的四路移相器网络系统进行仿真验证,结果表明,该方法能快速得到满足设计指标且具有稳定移相输出的移相网络.
