Smart transmitter system that includes apparatus for an automatic gain control circuit. The apparatus includes a circuit translates a transmit power control signal to produce a linear signal, and a first mapping circuit that maps the linear signal to a first control signal that is coupled to a variable gain amplifier (VGA). The apparatus also includes a power amplifier (PA) control circuit that receives the linear signal and a transmit signal to produce a second control signal that is coupled to a power amplifier.
