摘要： A surface acoustic wave filter has, on a piezoelectric substrate, surface acoustic wave resonators each composed of an interdigital transducer and reflectors disposed on both sides of the interdigital transducer. The surface acoustic wave resonators are arranged in series arms and in parallel arms to be connected in a ladder form. At least one of the surface acoustic wave resonators is replaced with an interdigital transducer that does not involve resonance in a propagation direction of a surface acoustic wave.
