摘　　要：通过某型号镜像阻抗连接结构低损耗SAW滤波器的设计过程,说明了在ADS软件中如何建立并调用各种模型来设计SAW滤波器,尤其是调用3D电磁场仿真软件计算出的封装性能,可以适应日益增高的器件工作频率和日益缩小的封装尺寸对仿真手段的要求。表面贴装器件实测结果与理论仿真基本吻合,满足了通带平滑低损耗高阻带抑制的要求,且过渡带陡峭。It is illustrated that how to build up and use kinds of model in ADS software to design a SAW image impedance connection filter in this paper. The most important is how to use the packaging result from 3D simulator for higher frequency and smaller packaging. The measured response of filter is consistent with the simulated response,with small ripple,low loss,high stop-band rejection and steep transition band response.
