摘要
在某些情况下,电路运用中需要用到不平衡输入-平衡输出结构的滤波器,该文基于三端口网络混合模S参数的原理,结合声表面波器件设计的COM模型,用ADS设计了Crf+Resonator混合结构的不平衡输入-平衡输出声表面波射频滤波器,该滤波器的仿真结果和实测结果吻合较好。
The SAW RF filters with unbalance-input and balance-output structure have to be used in the circuit in some applications. A Crf-bResonator hybrid SAW RF filter with unbalance-input and balance-output structure has been designed by using ADS design based on the mixed-mode S parameter of 3-port network and combining with COM model for SAW devices in this paper. The simulation results of SAW filter are agreed well with the simulation results.
