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. 

• • Our paper "A High Performance Complementary SiGe HBT Power Amplifier With A Three Conductor Coupled Line Four-Way Wilkinson Combiner Balun for Emerging K-band LEO SATCOM Transmit Front-End IC" won the first-place winner in GlobalFoundries design contest from 2026 IEEE RFIC Symposium. Congrats Seung Kyun Lee and Yoongoo Kang! Check the following article;
