Power Amplifier Measurement: Demo with Envelope Tracking - Part 5



Published
This series of videos talks about Power Amplifier (PA) measurement with Digital Pre-distortion (DPD) and Envelope Tracking (ET) technology using Keysight's PathWave X-Series Measurement Applications and PXIe VXT transceiver. ET is a technology recently used in wireless communication system's RF front-end which apply the variable voltage supply instead of fixed voltage supply for power amplifier. ET can increase the battery life, reduce heat dissipation, and improve PA performance. Keysight N9055EM0E Power Amplifier measurement application can support Digital Pre-distortion or Envelope Tracking technologies, and they can also be combined. Keysight ET test solution supports two kinds of configurations using 2-channel VXG + UXA/PXA or PXIe VXT + AWG. This video introduces the ET technology and demonstrates the envelop tracking using Keysight PXI VXT + AWG for 5G NR Power Amplifier testing.
