Abstract:
In a radio-frequency module, a hybrid filter includes an acoustic wave filter including at least one acoustic wave resonator, an inductor having a winding portion, and a capacitor. A plurality of outer electrodes of the acoustic wave filter includes a first input and output electrode connected to a first signal terminal, a second input and output electrode connected to a second signal terminal, and a ground electrode connected to a ground terminal. The inductor is disposed on a first major surface of a mounting substrate and is adjacent to the acoustic wave filter in plan view in a thickness direction of the mounting substrate. When viewed in a direction of a winding axis of the winding portion of the inductor, an inner part of the winding portion in the inductor does not overlap any of the first input and output electrode, the second input and output electrode, and ground electrode.
