Abstract
According to one embodiment, a power amplification apparatus includes an field effect transistor (FET), a first decoupling element, a power supply circuit, a second decoupling element, and a third decoupling element. The FET is arranged within a package having an input terminal and an output terminal, and power-amplify an input signal from the input terminal to a transmission signal. The first decoupling element decreases an inductance component of the transmission signal output from the FET. The power supply circuit supplies a driving power to the FET. The second decoupling element cut an RF component. The third decoupling element decreases an impedance of a drain bias circuit over a wide band.
