Abstract
To provide a radio-frequency module and a communication apparatus capable of achieving more excellent impedance characteristics. A radio-frequency module includes a first acoustic-wave filter (a first reception filter), a second acoustic-wave filter (a second reception filter), a switch (an antenna switch), a first inductor, and a second inductor. The first acoustic-wave filter transmits a signal in a first communication band. The second acoustic-wave filter transmits a signal in a second communication band. The first inductor is provided between ground and a node on a signal path (a second reception path) with which the switch is connected to the second acoustic-wave filter. The second inductor is connected in series between the switch and the first inductor on the signal path.
