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.
