Biography
Abdulrahman Alhamad is an assistant professor of Electrical and Computer Engineering in the Computer, Electrical and Mathematical Sciences and Engineering (CEMSE) Division at KAUST. He earned his Ph.D. in electrical and computer engineering from the University of California, San Diego.
Before joining KAUST, Alhamad was a senior technical staff member in the Silicon Engineering Group at Apple Inc., where he contributed to the development of 5G millimeter-wave (mmWave) cellular chipsets. He was also part of the Application-Specific Integrated Circuit (ASIC) Group at Nokia Bell Labs, working on advanced mmWave communication circuits.
At KAUST, he leads the Integrated Telecommunication and Sensing Systems (ITASS) group, focusing on millimeter-wave and sub-terahertz (>90 GHz) technologies for telecommunications and sensing applications. His research spans transceivers, phased arrays, radars and hybrid beamforming systems for 5G/6G telecommunications, satellite communications (SATCOM) and advanced sensing.
Alhamad has been recognized for his contributions to wireless communication and circuit design, including the Outstanding Designer Award from Analog Devices for his work on 5G multiband phased-array systems. His research has been featured in leading IEEE journals, including the Journal of Solid-State Circuits and the IEEE Microwave Theory and Technology Society.
Research Interests
Alhamad's research explores millimeter-wave and sub-terahertz technologies to advance high-speed wireless communication, satellite networks, and next-generation sensing systems. His specific areas of interest include:
- Sub-THz phased-array transceivers – Development of scalable, high-efficiency phased-array systems for ultra-high data rate wireless communications, addressing challenges in power efficiency, thermal management, and packaging
- High-resolution mmWave radars – Designing radar systems at 60 GHz, 70 GHz, and 140 GHz with sub-degree angular resolution for industrial monitoring, autonomous systems, robotics, and healthcare diagnostics
