Claim:
1. An electronic device, comprising: radio-frequency transmitter circuitry configured to transmit radio-frequency signals; power amplifier circuitry configured to amplify the transmitted radio-frequency signals; radio-frequency receiver circuitry coupled to an output of the power amplifier circuitry via a feedback path, wherein the radio-frequency receiver circuitry is configured to generate performance metric data based on the amplified radio-frequency signals; processing circuitry configured to generate calibration data for the power amplifier circuitry based on the performance metric data generated by the radio-frequency receiver circuitry; and circuitry that controls a gain provided by the power amplifier circuitry in amplifying the transmitted radio-frequency signals based on the calibration data, wherein the circuitry comprises storage circuitry that stores the calibration data, the calibration data comprises a data structure having a plurality of entries, and each entry of the plurality of entries has a corresponding output power level for the power amplifier circuitry and a corresponding bias voltage for the power amplifier circuitry.
