Optimization Design for Multi-channel Broadband Phase Shifter with Constant Difference Step

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.
