Abstract
A system and method for controlling envelope tracking in a transmitter with closed loop power control, including up-converting and pre-amplifying a baseband signal to a pre-amplified RF signal, amplifying the pre-amplified RF signal, converting the envelope of the baseband signal into a shaped envelope signal, adjusting the gain of the pre-amplified RF signal, and adjusting the shape of the envelope signal in response to changes in the gain of the pre-amplified RF signal.
