Welcome to the home page of Professor Inchan Ju at Ajou University. Our research interest lie in Silicon-based integrated high frequency electronics for wireless communication (5G/6G, Wi-Fi), Satellite Communication (SATCOM), Terahertz wireless communication, and other emerging applications. At present our research focus is mainly on energy-efficient, low cost wireless transmit/receive front-end integrated circuits using SiGe HBT BiCMOS and/or CMOS technologies for emerging 6G wireless communication.
