Tested with 5G NR signals
To evaluate the WPA-3342G-55 with modulated 5G signals, Wupatec used a power amplifier test setup based on the AMD RFSoC ZCU670 evaluation board. The setup runs Wupatec’s VST firmware and DPD, while measurement instruments analyse the signal at the amplifier output.
Take a look at the full measurement campaign to see how different 5G NR modulated signals perform when passed through the amplifier, with the test setup, graphs and detailed results.

OUR SOLUTIONS
Strong digital knowledge that is adaptable and reliable
Wupatec’s two pillars reside in its strong digital and analog knowledge. By having expertise in both fields RF and digital, we ensure DPD friendliness, or the amplifier’s behaviour can be anticipated during the design phase towards its final environment. Let’s work together.
