Abstract:
A radio-frequency module includes a first power amplifier, a second power amplifier, a switch, a plurality of first filters, and a second filter. The first power amplifier amplifies a transmission signal of a first frequency band and outputs the amplified transmission signal. The second power amplifier amplifies a transmission signal of a second frequency band and outputs the amplified transmission signal. The pass bands of the plurality of first filters are contained within the first frequency band. The pass band of the second filter is contained within the second frequency band. The second power amplifier has a greater output power level than the first power amplifier. The first output terminal of the first power amplifier is switchably connectable to the plurality of first filters via the switch. The second output terminal of the second power amplifier is connected to the second filter without the switch interposed therebetween.
