Title: Wideband mm-Wave Integrated Circuits and Phased-Array Systems for Multi-Standard Communication
Date/Time: 30 April 2025, 13:40
Location: FENS G029
The rapid growth in mobile users and high-bandwidth applications is creating unprecedented challenges and opportunities in telecommunications. As we address the need for higher data rates, the mm-Wave 5G bands have been expanded to accommodate this demand. With 6G on the horizon, targets are aiming for a 1 Tbps peak data rate, necessitating the allocation of even wider bands in the mm-Wave and sub-THz frequencies. Directive communications using affordable phased arrays have been adopted as a key technology for building mm-Wave communication systems to overcome the large free space path loss.
This talk will address the challenges associated with designing mm-Wave ultra-wideband integrated circuits and phased-array systems capable of operating over a widespread spectrum using advanced SiGe technology. Additionally, a recently introduced 64-element wideband scalable phased array design will be showcased, with a demonstration of the 20-50 GHz multi-band operation. The talk will conclude with the key opportunities and future directions in phased-array systems design.
Abdulrahman Alhamed is an Assistant Professor of Electrical and Computer Engineering (ECE) in the Computer, Electrical, and Mathematical Sciences and Engineering (CEMSE) Division at King Abdullah University of Science and Technology (KAUST). He earned his Ph.D. in Electrical and Computer Engineering from the University of California, San Diego (UCSD), USA. During his doctoral studies, Dr. Alhamed was a member of the Application-Specific Integrated Circuit (ASIC) Group at Nokia Bell Labs, contributing to the development of cutting-edge millimeter-wave (mmWave) communication circuits. Prior to joining KAUST, he worked as a Senior Technical Staff member in the Silicon Engineering Group at Apple Inc., focusing on 5G mmWave cellular chipsets. At KAUST, Dr. Alhamed leads the Integrated Telecommunication and Sensing Systems group dedicated to advancing millimeter-wave and sub-terahertz (>90 GHz) technologies for telecommunications and sensing applications. His research interests include transceivers, phased arrays, radars, and hybrid beamforming systems, with applications in 5G/6G telecommunications, satellite communications, and advanced sensing systems. Dr. Alhamed has received several recognitions for his contributions to the field, including the Outstanding Designer Award from Analog Devices in 2021 for his work on 5G multiband phased-array systems.
