Simplified PA characterization with envelope tracking presented at GSMA MWC 2015

Simplified power amplifier (PA) characterization including envelope tracking and digital predistortion has been demonstrated by Rohde & Schwarz at the GSMA Mobile World Congress 2015 in Barcelona. The test solution is based on the R&S^®SMW200A vector signal generator and the R&S^®FSW signal and spectrum analyser. The R&S^®SMW200A provides realtime RF and envelope signal generation plus digital predistortion in one instrument and the R&S^®FSW enables full PA characterization, including EVM, gain and distortion measurements.
