A
surface wave component contains at least two interdigital transducers having natural unidirectionality, disposed on a piezoelectric
crystal substrate, which form a
transducer pair consisting of transmission
transducer and reception
transducer. The transducers consist of an interdigital
electrode structure having prongs and
bus bars, and have opposite forward directions. At least two of the prongs form a transducer
cell that has at least one excitation center for exciting an electrical potential wave and at least one reflection center for reflection of electrical potential
waves, The transducer cells consist of two prongs having the same width, having a distance between the prong centers equal to half the length of a transducer period, whereby the
electrode structures of the two transducers consist of the same material, but have different layer thicknesses.
