Surface acoustic wave filter and duplexer component
Abstract:
A surface acoustic wave filter includes an arrangement of transducers having at least one first transducer one second transducer and one third transducer. The at least one first transducer is connected to the input terminal and a terminal for applying a reference potential. The second transducer is connected to the first output terminal and the terminal for applying the reference potential. The third transducer is connected to the second output terminal and the terminal for applying the reference potential. A capacitor is connected to at least one of a first and second output terminal in such a way that the capacitor is connected between the first and second output terminals or between one of the first and second output terminals and the terminal for applying the reference potential.
