Abstract
A first radio frequency (RF) power amplifier (PA) stage, a second RF PA stage, and an alpha RF switch are disclosed. The first RF PA stage provides a first RF output signal. During a first alpha mode, the alpha RF switch forwards the first RF output signal to the second RF PA stage, such that the first RF PA stage functions as a driver stage and the second RF PA stage functions as a final stage. However, during one of a group of alpha modes, the alpha RF switch forwards the first RF output signal to provide a corresponding one of a group of alpha transmit signals, such that the first RF PA stage functions as a final stage. Further, the first alpha mode is not one of the group of alpha modes.
