Abstract
An interdigital transducer for a surface acoustic wave includes an acoustic track with a width of BSges and subtransducers arranged adjacent to each other on the acoustic track and connected in series. The subtransducers include, in a transverse direction, n series subtransducers each having a track width of BSxi (i=1, 2, . . . n(x); n (x)≧2). In the subtranducers BSxi does not equal BS(x+1)i.
