摘要

SAW structure comprises a serial signal path arranged between an input gate and an output gate, a serial resonator (R) arranged in a serial branch and having a converter with partial electrodes (TE1, TE2) having regularly arranged electrode fingers (EF). A stub finger (SF) is assigned to each electrode finger of a partial electrode on opposite-lying electrodes. The stub fingers are separated by a gap (G). Preferred Features: A parallel resonator is arranged in the path which branches from the signal path. Neighboring stub fingers are short circuited using a short circuit structure.
