ABSTRACT:
A power amplifier includes amplifier stages. An amplifier stage includes a transistor, and at least one amplifier stage comprises a driver stage. The amplifier stages include a first amplifier stage having a first transistor and associated with a first output power, and a second amplifier stage having a second transistor and associated with a second output power. A current sharing coupling couples the first amplifier stage and the second amplifier stage. The first amplifier stage and the second amplifier stage share a current through the current sharing coupling. The current sharing coupling facilitates scaling of the first output power and the second output power.
