Abstract
(EN)
A multiplexer (1) comprises: a common terminal (110); a reception/output terminal (120, 130); a filter (20) connected between the common terminal (110) and the reception/output terminal (120); a filter (30) which is connected between the common terminal (110) and the reception/output terminal (130), and for which the pass band differs from that of the filter (20); and an impedance matching circuit disposed between the common terminal (110) and the filter (30). The impedance matching circuit includes a serial arm resonator (35) serially disposed on a path connecting the common terminal (110) and the filter (30).
