摘要

本文将报道一种全面的电导纳矩阵组成技术,包括与各种器件相对应的剩余电元件(电容、电感和电阻)的影响。利用上述组合程序,应用了基于优化方法的自动设计技术。自动设计程序确定SAW滤波器元件和外部电路元件的参数。这是可能的程序执行使用测量导纳矩阵元素。为了验证该方法的有效性,设计了用于数字移动终端的双带滤波器和双工器。发现这些器件的性能与设计预测很好地一致。

Automatic design procedure using circuit composition technique for SAW devices
A fully comprehensive electrical admittance matrix composition technique including the effects of residual electrical elements (capacitance, inductance and resistance) will be reported corresponding the various kind of the devices. An automatic design technique based on the optimization method is applied using the above composition routine. The automatic design procedure determines the parameters for SAW Filter elements and the external circuit element. It is possible that the procedure perform using measured admittance matrix elements. In order to verify the technique dual band filters and duplexers for digital mobile terminals were designed using the above procedure. The performance of these devices was found to be in good agreement with the design predictions.
