Abstract
A power amplification module includes a first input terminal that receives a first transmit signal in a first frequency band, a second input terminal that receives a second transmit signal in a second frequency band having a narrower transmit/receive frequency interval than the first frequency band, a first amplification circuit that receives and amplifies the first transmit signal to produce a first amplified signal and outputs the first amplified signal, a second amplification circuit that receives and amplifies the second transmit signal to produce a second amplified signal and outputs the second amplified signal, a third amplification circuit that receives and amplifies the first or second amplified signal to produce an output signal and outputs the output signal, and an attenuation circuit located between the second input terminal and the second amplification circuit and configured to attenuate a receive frequency band component of the second frequency band.
