Abstract
A linearity power amplification device is provided. The device comprises a divider, a combiner, n−1 first signal paths, and a second signal path coupled between the divider and the combiner. The first signal path comprises a main invariable attenuator connected to the divider, a first power amplifier connected to the combiner, and a first attenuator and a first shifter coupled between the first power amplifier and the main invariable attenuator. The second signal path comprises a main amplification circuit, and an error calibration circuit.
