Abstract
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.
Brief Biography
Abdulrahman Alhamed received the B.Sc. degree in Electrical Engineering from King Saud University, Riyadh, Saudi Arabia, in 2016, and the Ph.D. degree in Electrical and Computer Engineering from the University of California San Diego, La Jolla, CA, USA, in 2021. Dr. Alhamed joined the Application-Specific Integrated Circuit Group at Nokia Bell Labs, NJ, USA, in the summer of 2021 as a doctoral researcher, working on the development of millimeter-wave (mm-Wave) wireless communication integrated circuits. Between 2021 and 2023, he served as a Senior Engineer in the Silicon Engineering Group at Apple Inc., California, USA, working on the next generation of mm-Wave cellular chipsets. In 2023, Dr. Alhamed joined the College of Engineering at King Saud University, Riyadh, Saudi Arabia, where he is currently an Assistant Professor in the Department of Electrical Engineering. His current research interests include mm-Wave and sub-terahertz wireless transceivers and phased arrays for future telecommunication and sensing applications, such as 5G/6G technologies and Satellite Communication (SATCOM). In recognition of his work on the 5G multiband phased-array systems, Dr. Alhamed was awarded the Outstanding Designer Award in 2021 by Analog Devices.
