The architecture is based on the analog-digital combination by a multiplier and digital predistortion control circuit. The predistortion system generates an adaptive output signal to control the RF modulated signal that is the input signal of the power amplifier. The controlled and predistorted signal can contribute to drive a power amplifier with the cut-off static operation point into its amplifying region and simultaneously correct the non-linear distortion when the power amplifier operates to amplify an RF signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power amplifier predistortion methods and apparatus","description":"An embodiment of the invention is a predistortion approach to linearize a power amplifier by setting initially the static operation point of the power amplifier in the cut-off region.
