Abstract:
An acoustic resonator filter includes: a series unit including at least one series acoustic resonator electrically connected, in series, between first and second ports configured to pass a radio frequency (RF) signal; a first shunt unit disposed on a first shunt connection path between the at least one series acoustic resonator and a ground, the first shunt unit including a plurality of shunt acoustic resonators connected to each other in series and having different resonance frequencies; and a second shunt unit disposed in a second shunt connection path between the at least one series acoustic resonator and the ground, the second shunt unit including at least one shunt acoustic resonator and having higher inductance than inductance of the first shunt unit.
