Patent number: 12191828Abstract: 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.
