Chan-Sei Yoo

Chan-Sei Yoo (M'06–M'13) received the B.S. and M.S. degrees in electrochemical engineering in 1996 and 1998, respectively, and the Ph.D. degree in electronic and electrical engineering in 2010, all from Seoul National University, Seoul, Korea. In 1998, he joined the Electronic Materials & Device Research Center at the Korea Electronics Technology Institute, Gyeonggi, Korea, where he was involved in the development of microwave chip components using LTCC technology, such as chip inductor, chip capacitor, chip coupler, and chip balun. He then conducted research on the ceramic module-like dual-band voltage controlled oscillator for GSM/DCS application, dual-band antenna switch module for GSM/DCS application, and dual-band power amplifiers for KPCS/WCDMA and GSM/WCDMA applications. His current research focuses on the ultrawideband transceiver modules, radar systems for mm-wave application, and high-power and high-efficiency amplifiers, including switch-mode operation.
