摘要:
An elastic wave filter device in which elastic wave filters and parallel resonators are provided on a piezoelectric substrate includes a plurality of ground ports. The elastic wave filters include input-side resonators and output-side resonators. The input-side resonators are connected between a reception input port and a first one of the ground ports. The output-side resonators are connected between reception output ports and the first ground port. The parallel resonators are connected in parallel to output lines and are connected to second and third ground ports.
