In the department of mobile communication technology and satellite communication technology, wireless communication technology division is very important by transmitting and receiving the signals in wireless link environment. Most of all, the components which comprises the transmitter and receiver can decide the RF(Radio Frequency) system performances. Therefore to assure the reliability in the satellite communication field, it is essential to acquire the competitiveness by developing the highly integrated and compact components by means of MMIC(Monolithic Microwave Integrated Circuit) technology. MMIC is the designing and fabricating technology for the RF components. This paper introduces the MMIC technology and describes the technological trend and prospect in the satellite application.
