In the next five to 10 years, RF and microwave circuit design will undergo a revolution as the roles of artificial intelligence (AI) and machine learning (ML) shift from selectively applied enhancements to foundational layers inside relevant design environments. AI and ML will certainly never replace the analog intuition that makes RF/microwave engineers so valuable to their teams, but these computation engines promise major productivity gains and accelerated circuit optimization.

Traditionally, RF/microwave circuit design centers on a largely manual, simulation-heavy workflow. AI and ML facilitate a shift toward an “intent-driven” workflow, in which engineers specify goals and constraints while AI explores and optimizes the design space.

In an age in which ubiquitous connectivity is a primary system design consideration, the key challenges facing RF/microwave engineers bring significant opportunities for innovation. The discussion topics for this webinar may include the following:

•          Modern RF subsystems require multidimensional tradeoffs amongst parameters including gain, noise figure, linearity, power consumption, thermals, and more. What are some of the ways in which AI-driven design space exploration can help automate this optimization process?
•          Maxwell’s equations and semiconductor device physics will always and forever be at the heart of RF/microwave design methodologies. How will machine learning, informed by physics, reduce simulation times while preserving physical validity?
•       “Design a Ku-band filter with 1-dB ripple and minimum insertion loss under these substrate constraints.” Could generative RF design, deployed using AI prompts of this nature, become a real element in workflows?
•         What are some of the ways in which RFIC and MMIC design flows can be improved through ML-based device modeling toolkits?
•         Research is intensifying in areas like 6G and sub-THz frequency design, which are rife with optimization problems too complex for manual methods. What are the likely impacts of AI in the design of phased arrays, adaptive RF front ends, beamformers, cognitive radios, and dynamic spectrum allocation?
•        How will digital twins enhance multi-physics workflows to improve predictive failure analysis, automated circuit tuning, adaptive calibration, and lifecycle optimization in areas like aerospace/defense, automotive radar, and satellite communications?
•      Human RF expertise will never be replaced by automated design flows. But is it likely that the role of humans in the workflow will change as the influence of AI and ML rise? If so, how? Ultimately, are we moving toward “fully autonomous RF design,” or more of AI/ML as “co-pilots” in RF/microwave engineering?
•          What are the areas of design flows most likely to benefit the most from rapid AI integration?
•          What is the long-term outlook for RF and microwave EDA platforms with regard to AI/ML integration?
