摘要
提出了一种设计包含非谐振节点(NRN)元件滤波器的通用方法.文章指出传统耦合系数方法在设计包含NRN元件滤波器的缺点,通过广义耦合系数的等效电路模型建立统一的滤波器设计步骤,结合子结构的场仿真结果与子电路仿真结果相互逼近的仿真策略.并设计一款包含NRN元件的3阶E面波导滤波器,全波仿真结果满足滤波器的理论设计指标,证明该方法是正确和有效的.
In this paper, a general procedure is proposed to design the filter with non-resonance node（NRN）element. First, the paper points out the drawbacks of conventional design method based on coupling coefficient.Then, a general design procedure is presented based on the equivalent circuit model of the general coefficients.With the co-simulation between substructure and sub-schematic simulation strategy, a third-order waveguideE-plane band-pass filter is designed to prove feasibility of the proposed method. Performance of the filter isevaluated through simulation and show the feasibility and flexibility of the technique proposed in the paper.
