Abstract
Systems and methods are provided for calibrating the control mechanism in a communication circuit to allow the communication circuit to maintain a desired output power level. The communication circuit includes a variable gain adjustment circuit and a power amplifier, which operate together to provide an output power level. A control circuit controls the variable gain adjustment circuit based on a default gain parameter, a high power threshold, and a low power threshold. A calibration circuit in the control circuit calibrates a default gain parameter to provide a desired output power. A power detector can detect the desired output power level to provide an output power measurement. The calibration circuit calibrates upper and lower power thresholds to provide an acceptable range of power variation around the output power measurement.
