Abstract
A power amplifier module includes a first amplifier that amplifies a power level of a first input signal in a predetermined frequency band and outputs a first signal of a first power level; a first impedance transformer connected to the first amplifier and including a transmission line transformer; a second amplifier that amplifies a power level of a second input signal in the predetermined frequency band and outputs a second signal of the first power level; a second impedance transformer connected to the second amplifier and including a transmission line transformer; and a combiner that combines the first signal inputted through the first impedance transformer and the second signal inputted through the second impedance transformer into an output signal of a second power level larger than the first power level and includes a transmission line transformer.
