Principal Semiconductor Modeling Engineer for MMICs

nufactures compound semiconductor devices, microwave/millimeter-wave integrated circuits, and modules for defense applications. As a Principal MMIC Modeling Engineer working with our advanced GaN and GaAs technologies, you will be responsible for the generation of active and passive compact circuit simulation models to support the development of products fabricated in our III-V semiconductor foundry. These models will be used by our MMIC design teams across Raytheon to create Monolithic Microwave Integrated Circuits (MMICs) for use in advanced defense electronic systems. We value diverse skills and experience, so don’t hold back. Your qualification could add tremendous value to our team. Our customers come from all different backgrounds, and so do our employees. If you’re passionate about what you could accomplish here, we’d love to hear from you.

Responsibilities to Anticipate:

• Research and Development of advanced models for MMIC design using GaAs and GaN technologies, to accurately predict the static and dynamic behavior of currents and charges from DC to mm-Wave frequencies, including technology-inherent phenomena (https://e.g. traps, noise, statistics, linearity), as well as the electro-thermal environment.
• Develop design methodologies for high-performing PA, LNA, linear amplifiers, RF front-ends, and T/R chips (including RF switches and digital circuits), to optimize the performance and ensure circuit stability at the same time.    
• Design and layout of device modeling test structures (https://e.g. PA demonstrators) to assess model accuracy and demonstrate new design methodologies.
• Guide the MMIC design teams in performing accurate and efficient simulations of MMICs and modules and establish best-practices for MMIC design.
