IMS 2024

See our demo with our latest wideband GaN Doherty PA together with AMD Zynq RFSoC DFE and DPD

From the 16th to the 21st of June 2024, WUPATEC will be in  Washington DC attending the biggest conference specializing in RF and Microwaves of the world! It is organized and sponsored by the IEEE Microwave Theory and Techniques Society  (MTT-S).

We will be located at booth #1539, partnering with AMCAD Engineering and ITEST, showcasing the progress made in the RF PA design and advancements in the RFSoc. This combination of different areas of knowledge, digital and analogue, has made possible the bandwidth enlargement: this time, our PA covers the frequency 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.
