Envelope Tracking And Digital Pre-Distortion Test Solution For RF Amplifiers
By Rohde & Schwarz GmbH & Co. KG
An increasing number of power amplifiers (PA) support envelope tracking (ET) technology in order to reduce power consumption and improve efficiency. ET requires an additional generator to provide the envelope signal for the DC supply modulator. This application note introduces a test solution for characterizing PAs with ET using just a vector signal generator and a signal and spectrum analyzer, providing corresponding details and measurement examples.
