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 μs were used. An HP8753C automatic network analyzer was used to test the designed device
