A surface acoustic wave (SAW) filter includes at least one first electroacoustic transducer, and at least one second electroacoustic transducer. The at least one first electroacoustic transducer and the at least one second electroacoustic transducer are side-by-side inside an acoustic path having an aperture A0. The at least one first electroacoustic transducer is connected to an electrical output of the SAW filter, and the at least one second electroacoustic transducer is connected to an electrical input of the SAW filter. At least one first electroacoustic transducer comprises a series circuit of a number of partial transducers, wherein each partial transducer has an individual aperture that is reduced in relation to the overall aperture A0, and wherein the individual apertures add up to the overall aperture.
