    摘要： A filter includes a first filter that is connected between an input node and an output node and is a surface acoustic wave filter, and a second filter that is provided between the input node and the output node and is connected in parallel with the first filter. The first filter has a total number N1 of pairs of electrode fingers of interdigital transducers and the second filter having a total number N2 of pairs of electrode fingers of interdigital transducers, in which N1 is greater than N2.

    摘要： There is provided an apparatus that shows a much better transmission function characteristic in a signal passing band, and a low insertion loss. A plurality of pairs of electrode fingers constitute a first split electrode group of 5a1, 5b1, 5a2, 5b2, 5a3, 5b3, . . . . Further, a plurality of pairs of electrode fingers constitute a second split electrode group of 6a1, 6b1, 6a2, 6b2, 6a3, 6b3, . . . . The pairs of electrode fingers of both the groups are interleaved. The pairs of electrode fingers include electrode fingers of a width narrower than &lgr;/8 (&lgr; indicates the wavelength of a surface acoustic wave serving as the operation central frequency), and electrode fingers of a width wider than &lgr;/8, and the distance between the centers of the adjacent electrode fingers differs from &lgr;/4.
