A method for making an acoustic wave device (500, 600, 701, 801, 901, 1001), and an acoustic wave device (500, 600, 701, 801, 901, 1001) made by the method. The method comprises steps of providing a substrate (11) capable of supporting acoustic wave propagation and disposing a first transducer (518, 518') thereon. Disposing the first transducer (518, 518') includes disposing first through fourth electrode groups on the substrate. The first group couples to a first electrical interconnection (17+). The second group couples to a second electrical interconnection (17-). The third group couples to a common electrical interconnection and is interleaved with the first group of electrodes. The fourth group couples to the common electrical interconnection and is interleaved with the second group. The fourth group is disposed in an in-line configuration with the third group and is offset therefrom by an integral number of half-wavelengths of an acoustic wave corresponding to a center frequency of the acoustic wave device.
