ABSTRACT:
A base band of a λa wave generated by a λa/4 resonator is used as it is, a triple wave of the λa wave generated by the resonator is shifted to a low frequency side, and the fundamental wave and the triple wave are complemented by a pass band, generated by a λb/2 resonator. Consequently, a flat pass characteristic is secured in a band from the fundamental wave to the triple wave.
