    • An elastic wave filter has first, second, and third IDT electrodes whose wiring electrodes are connected to unbalanced signal terminal; fourth IDT electrode disposed between the first and second IDT electrodes; fifth IDT electrode disposed between the second and third IDT electrodes; and first and second balanced signal terminals connected to the wiring electrodes of fourth and fifth IDT electrodes, respectively. The ground electrodes of the first through fifth IDT electrodes are connected to the ground. Signals in opposite phase and in phase with a signal input to unbalanced signal terminal are output from first and second balanced signal terminals, respectively. The wiring electrodes of second and third IDT electrodes are adjacent to the ground electrode of fifth IDT electrode. The wiring electrode of one of first and second IDT electrodes is adjacent to the wiring electrode of fourth IDT electrode. The ground electrode of the other is adjacent to the ground electrode of fourth IDT electrode. This configuration can suppress spuriousness in the bandpass.

    • A surface acoustic wave (SAW) filter device includes an input port for receiving an unbalanced signal, a pair of input/output ports, a first SAW filter for receiving the unbalanced signal from the input port and outputting balanced signals to the pair of input/output ports, a second SAW filter for receiving the balanced signals output from the pair of input/output ports and outputting balanced signals, and a pair of output ports for outputting the balanced signals output from the second SAW filter. The first SAW filter includes a first longitudinally-coupled SAW resonator having a first unbalanced signal input port and first and second balanced signal output ports, and a second longitudinally-coupled SAW resonator having a second unbalanced signal input port and third and fourth balanced signal output port. The first and second unbalanced signal input ports are electrically connected to the input port. The first and third balanced signal output ports both are electrically connected to one of the pair of input/output ports. The second and fourth balanced signal output ports both are electrically connected to another of the pair of input/output ports. This SAW filter device can suppress spurious and has a small insertion loss.
