R&S SMW200A Generates RF And Envelope Signals In Realtime To Test Envelope Tracking Performance Of Power Amplifiers

2013-10-04 03:43:46| rfglobalnet News Articles

A major portion of amplifier power in smartphones dissipates as heat. The 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. Rohde & Schwarz offers a new option to test power amplifier ET performance. The R&S SMW200A high-end vector signal generator can now deliver RF and envelope signals in a single instrument.
