Thales UK Designs GaN MMIC/Packaging for MAGNUS Program Using NI AWR Software
Thales UK is a world-leading innovator across the aerospace, defense, ground transportation, security, and space industries. The company provides world-leading technology for both the civil and defense markets and its products impact the lives of people every day.
The Design Challenge
Thales UK is one of six companies from five European countries involved in designing products for the MAGNUS program, a European Defense Agency project aimed at developing European sourced application technologies for gallium nitride (GaN) on silicon (SiC). The technologies are used in advanced radar, communications, and electronic warfare systems covering the electromagnetic (EM) spectrum from 2-18 GHz.
Thales UK was responsible for the design of 10 W GaN monolithic microwave integrated circuit (MMIC) power amplifiers based on the United Monolithic Semiconductors (UMS) 0.25 µm foundry process. In parallel with this activity, package design and thermal analysis tasks were also performed. Once the MMICs had been realized and packaged, they were used to design a demonstrator unit, which Thales UK then leveraged to design a 30 W microwave power module (MPM).
The MMIC designs were carried out using NI AWR Design Environment, specifically Microwave Office circuit design software, the passive structures were simulated in AXIEM 3D planar EM simulator, and the package was analyzed in Analyst™ 3D finite element method EM simulator.
