Abstract

A dual operation mode power amplifier is disclosed. In the power amplifier in accordance with an embodiment of the present invention, a bias circuit part can be converted to decrease power consumption. Different from the prior art, performance of the present invention is not reduced in a high power mode, and no additional passive components like inductors or transformers with a large area are necessary to be further added. Furthermore, a tunable impedance matching circuit provides impedances respectively matching impedances of a fully differential amplifier and a single-ended amplifier, thereby improving the performance of the power amplifier.
