Patent ID: 7256654

Claim:
A power amplifier for amplifying a signal, comprising: a plurality of amplifier stages of the power amplifier, an amplifier stage operable to process the signal received by the power amplifier, an amplifier stage comprising a transistor, at least one amplifier stage comprising a driver stage operable to supply excitation to a next stage to amplify the signal, the plurality of amplifier stages comprising: a first amplifier stage having a first transistor, the first amplifier stage associated with a first output power; and a second amplifier stage having a second transistor, the second amplifier stage associated with a second output power and operable to operate under compression; and a current sharing coupling operable to couple the first amplifier stage and the second amplifier stage, the first amplifier stage and the second amplifier stage sharing a current through the current sharing coupling, the current sharing coupling operable to facilitate scaling of the first output power and the second output power.
