Last year, United Monolithic Semiconductors’ (UMS) introduced the GH10-10 GaN technology process that combines their proven III-V expertise with advanced process engineering to enable superior performance across demanding aerospace, defense, and broadband applications. GH10-10 empowers designers to push system capabilities further – achieving higher output power, improved thermal behavior, and greater design flexibility in compact, reliable solutions.
UMS’ GH10-10 is a new generation of GaN-on SiC technology that promises performance, good device robustness, and reduced memory effect with a combination of process and device optimization. Large signal measurements were performed at 18 GHz, 30 GHz, 45 GHz, and 60 GHz. The results at 45 GHz have shown more than 46% of PAE, 11 dB linear gain, and 2.5 W.mm-1 output power. At 60 GHz, a maximum PAE of 31-33% is obtained. The nonlinear electrical model accuracy is proven with the HPA designed at Q-Band, showing promising results.
Key Highlights of GH10-10
Recognized as a European supplier leader for innovative GaAs and GaN processes, UMS serves leading industries including defense, aerospace, telecommunications, automotive, and industrial markets. Driving innovation forward, UMS sets new standards in performance with GH10-10 for low-noise, RF switches and High-Power Amplifiers (HPA) MMIC solutions with unmatched efficiency.
Valeria Di Giacomo-Brunel, Head of UMS Product Solutions & Foundry Services, emphasized the importance of this new technology launch, stating: “GH10-10 represents a major leap forward in our technology roadmap, enabling high-frequency operation beyond V band with a good device robustness. By integrating GH10-10 technology into the market, our GaN platform reaches new levels of performance and capability, empowering more advanced and competitive solutions to push the boundaries of RF and mm-wave performance.”
UMS’ GH10-10 GaN technology is fully qualified and already opened in production mode, empowering their customers with high performance, fast time-to-market, and greater competitive advantages.
