1. A power amplifying module comprising:
a first input terminal that receives a first radio frequency input signal in a first operation mode;
a second input terminal that receives a second radio frequency input signal in a second operation mode, the second operation mode being different from the first operation mode;
a first power amplifier that amplifies the first radio frequency input signal and outputs a first amplified signal;
a stage matching circuit that is disposed downstream of the first power amplifier and that receives the first amplified signal;
a bypass line that bypasses the first power amplifier and outputs the second radio frequency input signal to an inside of the stage matching circuit; and
a second power amplifier that is disposed downstream of the stage matching circuit and that amplifies the first amplified signal or the second radio frequency input signal, and outputs a second amplified signal.
