Abstract
A radio-frequency module includes a module substrate having main surfaces opposite to each other, a hybrid filter having a first acoustic wave resonator, a first inductor, and a first capacitor, a switch for connecting and disconnecting an antenna connection terminal and the hybrid filter, and a coupler disposed on a path linking the antenna connection terminal and the switch. The first acoustic wave resonator is disposed on the main surface, the switch is included in a semiconductor IC disposed on the main surface, the coupler is disposed inside the module substrate, and in plan view of the module substrate, the semiconductor IC at least partially overlaps the first acoustic wave resonator, and the semiconductor IC and the coupler at least partially overlaps.
