Patent ID: 7738904

Claim:
A method for calibrating output power of communication circuitry that includes a gain tuning parameter, an upper power threshold, a lower power threshold, and a feedback loop at the communication circuitry that adjusts the gain tuning parameter based on the upper and lower power thresholds, wherein the gain tuning parameter adjusts the output power of the communication circuitry, the method comprising: setting the upper power threshold to an initial upper threshold, the lower power threshold to an initial lower threshold, and the gain tuning parameter to an initial tuning value; enabling the feedback loop at the communication circuitry; and while the feedback loop is enabled, performing a plurality of iterations at the communication circuitry for: measuring the output power of the communication circuitry to provide an output power measurement, configuring the gain tuning parameter of the communication circuitry based on the output power measurement and at least one of a previous iteration of said upper power threshold and a previous iteration of said lower power threshold, and adjusting at least one of the upper power threshold and the lower power threshold based on the gain tuning parameter.
