Rohde & Schwarz (Munich, Germany) has enhanced its new R&S SMW200A high-end vector signal generator by adding the R&S SMW K540 option for envelope tracking. This option enables quick and easy testing of envelope tracking power amplifiers for smartphones, base stations and tactical radios. Features include:
- Envelope tracking (ET) technique makes it possible to significantly enhance amplifier efficiency as it allows the amplifier supply voltage to track the envelope of the RF signal.
- Operates in a range close to its instantaneous maximum output power, considerably boosting amplifier efficiency.
- Using shaping functions, amplifier can be optimized for linearity or efficiency.
