1. An acoustic wave device arrangement comprising at least one piezo-electric substrate including N2 acoustic wave devices in which at the same operating frequency each of the devices have substantially the same electrical impedance and transfer characteristics, where N is an integer greater than unity, each device having at least one pair of terminals for coupling power into and out of said device, said N2 devices being electrically connected in a parallel-series arrangement comprising N groups each of which comprises N of said devices with the corresponding pairs of terminals being electrically connected in series, the corresponding pairs of terminals in each group being electrically connected in parallel with the corresponding pairs of terminals in the other group or groups whereby at said operating frequency the device arrangement has substantially the same electrical impedance and transfer characteristics as each of the individual N2 devices.
