Thales UK Designs GaN MMIC/Packaging for European MAGNUS Program Using NI AWR Software


Thales UK, a world-leading innovator across the aerospace, defense and space industries, designed a gallium nitride (GaN) monolithic microwave integrated circuit (MMIC) power amplifier (PA) for the MAGNUS program, a European Defense Agency project aimed at developing European-sourced application techniques for advanced radar, communications and electronic warfare systems. Thales UK was responsible for developing a 10 W GaN MMIC PA based on the United Monolithic Semiconductors (UMS) 0.25 micrometer foundry process, as well as the package design and thermal analysis. The MMIC designs were carried out using NI AWR Design Environment, specifically Microwave Office circuit design software, the passive structures were simulated using AXIEM 3D planar EM simulator, and the package was analyzed with Analyst™ 3D finite element method EM simulator.

“Our design and simulation efforts showed that the UMS PDK, as well as the Microwave Office and Analyst models, were very accurate, which led to the success of this project,’’ said Rashid Fazaldin, microwave design engineer at Thales UK.
