High-frequency module
A filter unit of a high-frequency module includes a plurality of SAW resonators connected in series between a first series connection terminal and a second series connection terminal, first shunt connection terminals, a second shunt connection terminal, and a plurality of SAW resonators. A connection line interconnecting the SAW resonators is connected to the first shunt connection terminal through one of the SAW resonators. The first shunt connection terminal is connected to a ground through an inductor. A matching circuit is connected between the second series connection terminal and a second external connection terminal. The matching circuit is inductively or capacitively coupled to the inductor.
