2019 International Microwave Symposium: Workshops and Short Courses
Modern electromagnetic simulation is founded on the vision that all electronic design is fundamentally based on Maxwell’s Equations, thus solving them directly would one day become the basis for the highest performance design. That day is today.
In this workshop presentation, Dr. Williams will show how engineers deliver design innovation for 5G RF front-end systems using advanced physics-based simulation. You will see that modern challenges for the RF channel including antennas, RF front-end modules, and radio circuits can be addressed using electromagnetic and multiphysics tools.
Industry examples include an active phased array antenna system for real-time beamforming, and how modern electromagnetic field solvers combine with circuits and systems for RF module and base station RF system modeling.
Critical in modern RFIC module design for both sub-6GHz and mm-wave design is the ability to create layout-based design assemblies. That design capability will be covered to illustrate how a combination of multi-die laminate structures can be assembled and then analyzed for electrical and electro-thermal performance.
5G systems require significant signal processing and data center switching resulting in new challenges in chip, package, printed circuit board integration. Dr. Williams will briefly highlight some examples of edge computing challenges of electrical signal integrity, power integrity, thermal behavior, and EMI.
Applications of 5G for future Autonomous vehicles and smart cities will also be explored illustrating challenges and opportunities. The presentation concludes with Dr. Williams’ vision on what the future will bring and how it will impact organizations that embrace it.
