Abstract
Exemplary embodiments are related to method and devices for calibration a radio-frequency (RF) transceiver. A method may include calibrating an RF device by calculating input voltage values and bias voltage values of a power amplifier for each desired output voltage value of the power amplifier to generate a desired compression point. The method may also include applying digital pre-distortion (DPD) values to the input voltage of the power amplifier, and measuring a value of the output voltage after applying the DPD values.
