RF Power Amplifier Test Platform

In order to characterize its own RF power amplifiers, Wupatec has developed ifirmware in order to control the different components of the RFSoC. It divert its use and make it an equivalent of Vector Signal Transceiver or test platform. Wupatec therefore offers its developments, either as part of a measurement service or in the provision of a test platform dedicated to the characterization of amplifiers at the customer’s premises.

Based on ADRV9009 Transceivers or the latest RFSoC ZCU670 from AMD, our test platform are able to perform both CW and Pulsed RF Signal measurement (Configurable pulse rise/fall timings in pulsed mode).

Allowing 1 or 2 Tones measurement, the aim of those test benches are 5G modulated signals measurement to characterize the power amplifier linearity performances.

Using the RFSoC as an integrated vector signal generator (VSG) and vector signal analyzer (VSA) allows us to perform IQ Modulation and Demodulation thanks to the IQSTAR Software from AMCAD that drives the all setup. We are able to do acquisition averaging up to 8192 in IQ modulation mode for high dynamic range characterization.

Test benches embed closed loop CFR and DPD either from commercial solution or from Wupatec DPD and CFR IP and also able us to perform evaluation of customers DPD.
