Abstract

CAD tools for designing interdigital surface-acoustic-wave (SAW) devices are presented. The software computes the exact spatial position of the metal interdigital electrodes for any given chirp specification. A linear FM up-chirp SAW device was designed with the CAD tools, with one dispersive and one wideband transducer (dual in-line geometry). The device was designed to produce a chirp pulse with a rectangular window envelope using four electrodes per period. A center frequency of 100 MHz, a bandwidth of 10 MHz, and a pulse duration of 2 mu s were used. An HP8753C automatic network analyzer was used to test the designed device.<>

用于表面声波啁啾器件设计和分析的CAD工具

介绍了用于设计数字间表面声波(SAW)器件的CAD工具。该软件计算金属数字间电极的精确空间位置为任何给定的啁啾规格。利用CAD工具设计了一种线性调频上调频声表面波器件，该器件具有一个色散换能器和一个宽带换能器(双直线几何结构)。该装置被设计为产生一个具有矩形窗口包络的啁啾脉冲，每个周期使用四个电极。中心频率为100 MHz，带宽为10 MHz，脉冲持续时间为2 μ s。采用HP8753C自动网络分析仪对设计的装置进行了测试。
