ABSTRACT:
A method and apparatus is provided for use in power amplifiers where multiple parallel power amplifiers provide various output power levels. By selectively enabling and disabling the parallel power amplifiers and combining their outputs, a desired output power can be realized, while choosing a combination of power amplifiers that provide a high efficiency.
