| 摘 要： | 提出了采用PSPICE仿真声表面波器件的方法,它将叉指换能器一个周期段Mason等效电路复阻抗采用LC串并联网络等效,并以子电路形式由叉指换能器等效电路调用,两换能器间声传播路径采用等延迟时间的无损耗传输线等效,同时考虑外电路影响,仿真得到的异型声表面波器件的幅度特性与实测结果基本相符。

| Abstract: | A method to simulate surface acoustic wave device(SAWD) is proposed,in which impedances of Mason equivalent circuits are equaled by LC networks called as subcircuit,and piezoelectric material between input and output interdigital transducers are equaled by non-loss transmission line with the same delay time.Non-conventional type SAWD including external circuit is simulated by PSPICE,and the results are near to measurements. |
