Abstract
A PA module () includes multiple amplifying elements () and a variable filter circuit (). The amplifying elements () amplify a transmission signal in a frequency range including multiple communication bands and are cascade-connected to each other. The variable filter circuit () is connected between the amplifying elements (). The variable filter circuit () uses a transmission band corresponding to a used communication band selected from the multiple communication bands as a pass band and a reception band corresponding to the used communication band as an attenuation band.
