Responsibilities
Advanced Multiphysics Modeling: Utilize CST Studio Suite to perform coupled EM-Thermal simulations. Quantify how RF losses (insertion loss, dielectric loss) translate into thermal loads
Electronics Packaging: Aid in the design and optimization of enclosures for SWaP-constrained environments, ensuring high-power components like GaN (Gallium Nitride) power amplifiers remain within junction temperature limits
Environmental Compliance: Ensure all mechanical designs meet stringent DoD survivability requirements, including thermal shock, solar radiation, and extreme ambient operating temperatures
Subsystem Integration: Direct the design of advanced cooling solutions, including micro-channel liquid cooling, phase-change materials (PCM), and high-conductivity thermal interface materials (TIMs)
Qualification
