HIGH-FREQUENCY MODULE

摘要

A filter unit (20) of a high-frequency module (11) is provided with a plurality of SAW resonators (201-208) serially connected to a first serial connection terminal (P21) and a second serial connection terminal (P22), first shunt connection terminals (P231, P232), a second shunt connection terminal (P24), and a plurality of SAW resonators (211-214). A connection line connecting the SAW resonators (202, 203) is connected to the first shunt connection terminal (P231) via the SAW resonator (211). The first shunt connection terminal (P231) is connected to ground via an inductor (50). A matching circuit (42) is connected between the second serial connection terminal (P22) and a second external connection terminal (P2). The matching circuit (42) is inductively or capacitively coupled to the inductor (50).
