Abstract
A frequency sensitive ASW structure is presented, operating by reflection of acoustic surface waves. Such a structure is of interest for frequency filters and filter banks. The response can be computed by scattering matrices leading to a good agreement with experimental results. Different configurations like fan shape electrodes can be used. In this paper, a 5-channels filter bank with a relatively good frequency separation between adjacent channels is presented. The relevant parameters like insertion loss, rejection, number of channels will be discussed and the other possible applications are described. This device meets the requirements of a frequency division multiplex.
