Abstract:
A multiplexer includes filters, a common terminal with which an inductance element is connected to a connection path of the common terminal and an antenna element and a capacitance element is connected in series to the connection path, and another inductance element. An input terminal of one of the filters is connected to the common terminal via the another inductance element, and is connected to a parallel resonator. In each of the filters other than the one filter, one of the input terminal and the output terminal, which is a terminal closer to the antenna element, is connected to the common terminal, and is connected to the series resonator.

Claim (Index 19):
An impedance matching method of a multiplexer that transmits and receives a plurality of high-frequency signals via an antenna element, the method comprising:\n adjusting a plurality of elastic wave filters with passbands that are different from each other, such that when viewing one elastic wave filter of the plurality of elastic wave filters from one of an input terminal and an output terminal of the one elastic wave filter, complex impedance at passbands of other elastic wave filters of the plurality of elastic wave filters is in a shorted state, and when viewing each of the other elastic wave filters from one of the input terminal and the output terminal of each of the other elastic wave filters alone, complex impedance at passbands of the other elastic wave filters is in an open state; adjusting inductance values of a filter matching inductance element such that complex impedance when the filter matching inductance element is connected in series to the one elastic wave filter, when viewing the one elastic wave filter from the filter matching inductance element side, and complex impedance when the other elastic wave filters are connected in parallel to the common terminal, when viewing the other elastic wave filters from the common terminal side, are in a complex conjugate relationship; and adjusting, in a compositing circuit in which the one elastic wave filter is connected to the common terminal via the filter matching inductance element and the other elastic wave filters are connected to the common terminal in parallel, at least one first circuit element connected between a connection path of the antenna element and the common terminal, and a reference terminal, and at least one second circuit element connected in series to the connection path of the antenna element and the common terminal, such that complex impedance when viewed from the common terminal matches a characteristic impedance; wherein in the adjusting of the plurality of elastic wave filters, among the plurality of elastic wave filters including at least one of a series resonator connected between an input terminal and an output terminal, and a parallel resonator connected between a connection path connecting the input terminal and the output terminal and a reference terminal, at the one elastic wave filter, the parallel resonator and the series resonator are arrayed so that the parallel resonator is connected to the filter matching inductance element, and at the other elastic wave filters, the parallel resonator and the series resonator are arrayed so that the series resonator, out of the parallel resonator and the series resonator, is connected to the common terminal.
