Gwanghyeon Jeong is an Associate Professor in the Department of Semiconductor System Engineering at Hanbat National University, South Korea. He received his B.S., M.S., and Ph.D. degrees in Electrical Engineering from the Korea Advanced Institute of Science and Technology (KAIST) in 2012, 2014, and 2018, respectively. Following his doctoral studies, he served as a Researcher at the Agency for Defense Development (ADD) from 2018 to 2021. He then transitioned to academia, serving as an Assistant Professor at Hannam University (2021–2024) before joining the faculty at Hanbat National University. Currently, he is the director of the HBNU RF Laboratory, leading research on high-performance RF and microwave integrated circuits. His primary research interests focus on the design and implementation of RF circuits and systems for future wireless communications. His expertise encompasses the development of various front-end components, including Power Amplifiers (PA), Low Noise Amplifiers (LNA), and RF Switches (SW). By integrating these key elements, he focuses on the optimization of RF Front-End Modules (FEM) utilizing various semiconductor processes such as GaAs, GaN, and CMOS to enhance the performance of 5G/6G and satellite communication systems.
