DEMO 2024
We hope you enjoyed the European Microwave Week (EuMW) 2024 as much as we did! From WUPATEC, we were excited to have you visit our booth and discover our latest innovations.
It was a pleasure meeting you in Paris, discussing your needs, and showcasing our solutions!
DEMO 2024

We will be located at booth #601, partnering with AMCAD Engineering and AMCAD SAS, showcasing the progress made in RF PA design and advancements in the RFSoc. This combination of different areas of knowledge, both digital and analog, will make bandwidth enlargement possible: this time, our PA will cover the frequency range of 3.3 GHz to 4.2 GHz with 600 MHz of instantaneous bandwidth.
The demonstration shows a 2-stage 8W average high-efficiency power amplifier operating in C band. This Doherty power amplifier using commercial GaN on SiC devices from Qorvo covers 3.3 GHz to 4.2 GHz, with 47.5 dBm peak power, 28 dB of linear gain, PAE higher than 35 % @8dB OBO and high linearity <-55 dBc ACLR with DPD and 5G NR one carrier of 100 MHz. The instantaneous bandwidth easily reaches 600MHz of the RF frequency band.
In collaboration with AMD this demonstration uses the latest Zynq™ UltraScale+™ RFSoC DFE (evaluation board ZCU670) together with AMD’s latest DPD and CFR IP. With Wupatec’s firmware, the RFSoC DFE is controlled using IQSTAR software from AMCAD Engineering which allows a comprehensive characterization of the RF power amplifier in an environment close to the final implementation of the radio unit.
