Claim Text:
1. A power amplifier module comprising: a first signal input terminal to which a first radio frequency signal of a first frequency band is input; a second signal input terminal to which a second radio frequency signal of a second frequency band is input; first, second, and third power amplifiers; a bias control circuit; a shunt connection terminal that is electrically connected between an output terminal of the first power amplifier, an output terminal of the second power amplifier, and an input terminal of the third power amplifier; and a third inductor of which a first end is electrically connected to the shunt connection terminal and a second end is grounded, wherein the first signal input terminal and an input terminal of the first power amplifier are electrically connected to each other, wherein the second signal input terminal and an input terminal of the second power amplifier are electrically connected to each other, wherein the output terminal of the first power amplifier is electrically connected to the output terminal of the second power amplifier and the input terminal of the third power amplifier at a connecting point, wherein the bias control circuit performs a control process of supplying a bias current to one of the first and second power amplifiers depending on a frequency band selected from the first and second frequency bands, wherein the first and second signal input terminals are formed on a first side of a semiconductor integrated circuit, wherein the shunt connection terminal is formed on a second side of the semiconductor integrated circuit, the second side of the semiconductor integrated circuit being adjacent to the first side of the semiconductor integrated circuit, and wherein a direction of wires connected to the first and second signal input terminals and a direction of a wire connected to the shunt connection terminal are perpendicular to each other.
