Microwave Circuits and Modules (MCM) Lab

About the Lab

Since 2010, we have been working on microwave circuits and modules for wireless communications, optical communications, and radar applications. We are designing integrated circuits using CMOS, GaAs, and GaN technologies and developing modules on printed circuit boards using commercial chips. Recently, we are also developing ultrasonic circuits for humidifiers and algae control applications.
