Abstract
Disclosed herein are systems and methods for using a digital power amplifier controller (DPAC) having forward-loop correction and feedback-loop correction. In an embodiment, the DPAC receives, via an analog-to-digital converter (ADC), a digital power-measurement signal from a power sensor coupled to an output of a power amplifier. The DPAC adjusts (e.g., linearizes) the digital power-measurement signal using a measurement-correction function for the sensor, and uses the adjusted digital power-measurement signal to generate a digital feedback signal, which the DPAC uses to generate a digital power-control signal that reflects a desired power level at the output of the power amplifier. The DPAC adjusts (e.g., linearizes) the digital power-control signal using a control-correction function for the power amplifier, and outputs the adjusted digital power-control signal via a digital-to-analog converter (DAC) to a power-control node of the power amplifier.
