Abstract
In one embodiment, the present invention includes multiple gain stages and an output network coupled to the gain stages. Each of the gain stages can be independently controlled to amplify a radio frequency (RF) signal to an output power level for transmission from a mobile wireless device. When controlled to be inactive, at least one of the gain stages can be placed into a low impedance state.
