摘　　要：本文介绍了隐式空间映射算法的原理与步骤,在此基础上采用ADS原理图模型作为粗略模型,采用Agilent Momentum来实现精细模型响应,将谐振器间的耦合微带线厚度与介电常数作为参数提取变量,通过设计一个发夹形滤波器,优化得到了比指标性能更优越的结果。证明了该算法具有操作简单、较快的逼近速度和较高的优化效率等优点。The principle and steps of implicit space mapping algorithm was introduced. As a coarse model, ADS schematic model is adopted to approximate the fine model that is realized by Agilent Momentum. Thickness and dielectric constant of the coupling microstrip line between the resonator as parameter extraction variables, a hairpin filter is designed. The results are better than the design specifications. The new algorithm is verified faster and more efficient, at the same time this method is simple to operate.
