이동통신 및 위성통신 분야에 있어서 무선통신기술은 무선환경에서 신호를 보내고 받는 기능을 수행하는 중요한 분야이다. 이러한 무선통신 분야에서 송수신단을 구성하는 송수신 부품은 RF 시스템의 성능을 좌우한다. 특히, 위성통신 분야에서 신뢰성을 획득하기 위해서는 고집적화와 소형화를 통한 경쟁력 확보가 필수적인데 이를 위한 기술이 MMIC이다. MMIC 기술이란 반도체 공정을 이용하여 RF 부품을 설계하고 제작하는 기술로써 본 고에서는 MMIC 기술 소개와 이동통신 및 위성분야에서의 MMIC 기술 동향과 개발 현황, 앞으로의 전망을 개괄적으로 서술하고자 한다.
