Abstract: Apparatus and methods for envelope tracking calibration are provided. In one embodiment, a power amplifier system includes a power amplifier, an envelope tracker that generates the power amplifier's supply voltage, a power detector, and a calibration module. The envelope tracker includes an envelope shaping table generated at a desired gain compression and a scaling module that scales an amplitude of an envelope signal. The power detector measures the power amplifier's output power, and the calibration module provides calibration data to the scaling module to change the scaling of the envelope signal's amplitude. The calibration module sets the calibration data to a first value corresponding to a supply voltage level associated with substantially no gain compression, and reduces the supply voltage level by changing the calibration data until the power detector indicates that the gain compression of the power amplifier is about equal to the desired gain compression.

Abstract: Apparatus and methods for envelope tracking calibration are provided. In one embodiment, a method of calibrating an envelope tracker having an envelope shaping table generated at a desired gain compression of a power amplifier is provided. The method includes generating a supply voltage for the power amplifier using the envelope tracker, operating the supply voltage of the power amplifier at a first voltage level associated with substantially no gain compression of the power amplifier, and measuring an output power of the power amplifier at the first voltage level. The method further includes decreasing a voltage level of the supply voltage one or more times and measuring the output power at each voltage level, determining a second voltage level of the power amplifier associated with a gain compression equal to about that of the desired gain compression, and calibrating the envelope tracker based on the determination.
