실험실 소개

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.
우리 연구실은 2010년 부터 무선 통신, 광통신, 레이다 응용 분야의 초고주파 회로와 모듈을 개발하고 있습니다. 현재 CMOS, GaAs, GaN 트랜지스터 기술을 이용한 집적 회로 설계를 하고 있고, 상용칩을 활용하여 PCB에 모듈을 개발하는 일을 하고 있습니다. 최근에는 초음파 가습기와 초음파 녹조제거기를 위한 초음파 회로 또한 개발하고 있습니다.
