IWTu6: Reconfigurable Wideband Phased Arrays for mmWave: System Design and Verification Across Radar and Wireless Domains

Presentation Abstract
The evolution of wireless systems toward higher frequencies, together with the integration of joint RF sensing and communications, drives unprecedented demands on phased array performance. Next-generation architectures must deliver exceptional transmitter linearity and receiver sensitivity across multi-gigahertz bandwidths and large antenna arrays. We explore advanced measurement and behavioral modeling techniques, linking hardware prototypes with digital twins to accelerate the exploration of architectures and the development of wideband adaptive analog and digital algorithms, emphasizing the balance between modeling accuracy and computational efficiency. Demonstrations highlight design trade-offs and performance optimization strategies relevant to both 5G/6G communication links and AESA radar systems.
