Abstract
A method for calibrating a supply voltage of an envelope tracking PA (power amplifier) is provided. The method includes obtaining a plurality of calibrated PA supply voltage values using a PA output power sequence having a plurality of different PA output power values. Thereby, an order of the PA output power values of the PA output power sequence is chosen such that a junction temperature of the PA is maintained during calibration within a temperature range that occurs during non-calibration envelope tracking operation.
