Abstract:
Envelope trackers providing compensation for power amplifier output load variation are provided herein. In certain configurations, a radio frequency (RF) system includes an antenna, a power amplifier that receives a radio frequency signal and outputs an amplified radio frequency signal to the antenna, a plurality of detectors coupled to the power amplifier and operable to generate a plurality of detection signals, and an envelope tracker that controls a supply voltage of the power amplifier based on an envelope of the radio frequency signal. The envelope tracker processes the plurality of detection signals to generate a load variation detection signal indicating a change in an output load of the power amplifier arising from a change in a voltage standing wave ratio (VSWR) of the antenna. Additionally, the envelope tracker adjusts a gain of the power amplifier based on the load variation detection signal.

Claim (Index 5):
The radio frequency system of  claim 1  wherein the plurality of detection signals includes an input detection signal and an output detection signal, the envelope tracker further configured to generate the load variation detection signal based on compensating an output load variation indicated by the output detection signal by a nominal output load variation indicated by the input detection signal.
