An extended power ramp table for a power amplifier control loop in a time division multiple access (TDMA) communication system includes a power profile data table and a control data table. The power profile data are used to control transitions of the power amplifier circuit between its on and off states to minimize the number and power levels of spurious and other undesired signals generated by such on and off circuit state transitions. The control data are used to programmably control various performance characteristics of the control loop for the power amplifier circuit, such as controlling the gain of the driver amplifier for the power amplifier control (or reference) signal, controlling the gain and offset of the feedback amplifier for the control loop, and selectively providing a bias current for an external power detection diode. By making the control data user programmable, maximum flexibility in controlling the power amplifier control loop can be achieved.
