Abstract
최근 국내에서는 MATV(Master Antenna Television: 텔레비전 공동시청 설비)를 SMATV(Satellite Master Antenna Television)로 개정함에 따라 공동주택의 방송설비는 지상파 방송, FM 라디오 방송과 함께 위성방송을 의무적으로 통합하여 전송하도록 개정하였다. 국외의 경우 대부분의 나라에서 SMATV가 기본적으로 허용된데 반해 국내에서는 케이블 방송과 위성방송 서비스 업체간의 이익 분쟁으로 인해 SMATV용 혼합형 증폭기에 대한 기술 개발 및 양산이 미진한 상태에 있다. 따라서, 본 연구에서는 지상파 텔레비전 방송대역(54~806Mhz)과 FM 라디오 방송대역(88~108Mhz) 뿐만 아니라 위성방송 대역(950~2150Mhz)까지 증폭할 수 있는 광대역 증폭기를 개발하고 그에 따른 문제점의 해결방안을 제시한다. Recently n Korea, the House of Commons and terrestrial broadcasting facilities integrated with FM radio and the satellite compulsory was amended to transfer MATV(Master Antenna Television) adjusted by SMATV(Satellite Master Antenna Television). While the SMATV was accepted by default in most other countries, our county did not accept it as the default for broadcast. Because domestic cable and satellite television service providers are conflicts with their interest. bAs a result, the hybrid amplifier for SMATV technology development and volume production for the state is insufficient. Therefore, terrestrial television broadcast bands (54 ~ 806Mhz) and FM radio broadcast band (88 ~ 108Mhz) band satellite with (950 ~ 2150Mhz) to amplify the development of a broadband amplifier with subsequent resolution of problems is also presented in this study.
