Doctoral student Yiyang Song of the University of Michigan – Shanghai Jiao Tong University Joint Institute (UM-SJTU JI, JI hereafter) has won the Best Student Paper Award at the 2024 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications. His award-winning paper, titled “A K-band Power Amplifier Designed Based on 65 nm CMOS Process,” was selected from over 300 articles by scholars from around the world at the international seminar held in Nanjing from November 8 to November 11.
Power amplifiers (PAs) are crucial components in wireless communication systems, used to amplify signals for antenna transmission. Their performance directly impacts the efficiency and quality of wireless transmission, with applications spanning mobile devices, satellite communication, automotive radar, and imaging. Under the guidance of JI Associate Professor Xuyang Lu, Yiyang Song’s research starting in late 2023 focused on the design of RF power amplifiers. Leveraging techniques such as on-chip baluns, neutralization capacitors, and switch transistors, the research aims to improve drain efficiency, reduce overall DC power consumption, and enhance stability and linearity.

The award certificate
Song, a doctoral student in Electronics Science and Technology who just graduated from the JI undergraduate Electrical and Computer Engineering program this year, attributed his success to the JI experience,” The circuit courses during my undergraduate studies opened the door to electronic engineering for me. I found the combination of theoretical knowledge and practical implementation in hardware design captivating. It’s deeply fulfilling to tackle complex problems and see real-world applications materialize from my work.”
Song’s advisor Xuyang Lu is an associate professor jointly appointed by JI and the Department of Electronic Engineering of SJTU. As a doctoral supervisor and a recipient of national-level young talent recognition, Lu’s research focuses on RF, millimeter-wave, terahertz, and near-infrared optical integrated circuit design. His work has been published in leading journals such as Nature Electronics, ISSCC, and JSSC. He has received numerous honors, including the IEEE Predoctoral Fellowship, Forbes 30 Under 30, and the Xiaomi Scholarship at Shanghai Jiao Tong University.
