Abstract:
Provided is a power amplification module that supports a plurality of communication systems. The power amplification module includes: two power amplifiers that can be selectively connected in parallel with each other; a switch that, in accordance with one communication system selected from among the plurality of communication systems, selects one power amplifier that is to operate by itself from among the two power amplifiers or selects the two power amplifiers and connects the two power amplifiers in parallel with each other; and a phase correction circuit that, when the two power amplifiers are both selected, corrects a phase difference by being selectively connected between the outputs of the two selected power amplifiers such that a phase difference is not generated between the output signals of the two selected power amplifiers.
