ROHDE & SCHWARZ
An increasing number of power amplifiers (PA) support the envelope tracking (ET) technology in order to reduce power consumption and improve efficiency, for example in smartphones and tactical radios. Typical setups to test PAs consist minimally of a signal generator and a spectrum analyzer. Envelope tracking requires an additional generator to provide the envelope signal for the DC supply modulator. Rohde & Schwarz offers a compact solution for characterizing power amplifiers with envelope tracking using the SMW vector signal generator and the FSW signal and spectrum analyzer, effectively replacing complex test setups.
