Abstract

PURPOSE:A normal-electrode-structured elastic surface wave element and a weightedelectrode-structured elastic surface wave element are combined together to obtain intermediate characteristics between the both elastic surface wave elemnts, thereby aking the insertsion loss larger than that of the weighted-electrode-structured one.
