Abstract:
A power amplification module includes first and second amplifiers for first and second communication modes, a bypass line that bypasses the first or second amplifier, an input switch circuit that supplies a radio frequency signal to the first or second amplifier in accordance with a communication mode when a desired output level is equal to or greater than a reference level, and that supplies a radio frequency signal to the bypass line when the desired output level is less than the reference level, and an output switch circuit that outputs a first amplified signal from the first amplifier or a second amplified signal from the second amplifier in accordance with the communication mode when the desired output level is equal to or greater than the reference level, and that outputs a radio frequency signal output from the bypass line when the desired output level is less than the reference level.
