Envelope Tracking and Digital Pre-Distortion Test Solution for RF Amplifiers

Source: 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. In an attempt to significantly reduce the amount of hardware needed for testing these amplifiers, Rohde & Schwarz has combined the R&S®SMW200A with the R&S®FSW to form a state-of-the-art testing solution. This application note presents an in-depth overview of the test solution while presenting corresponding measurement examples.
