Claims (5)
- 복수개의 혼들로부터 수신된 신호들의 잡음지수 증가를 억제하고, 신호원의 크기를 증가시키는 복수개의 LNA들;상기 복수개의 LNA들의 출력신호들을 받아서 소정 대역 주파수의 교류성분만을 통과시키는 켜 출력을 얻는 복수개의 BPF들;복수개의 국부발진기들;상기 복수개의 BPF들로부터 출력되는 RF신호들을 상기 복수개의 국부발진기들에서 발생되는 신호들을 이용하여 소정 대역의 IF신호로 다운 컨버팅하는 복수개의 믹서들;상기 복수개의 믹서들을 SVR에서 처리하기에 충분한 크기의 신호들로 증폭시키는 복수개의 IF앰프들;상기 복수개의 IF앰프들로부터 출력되는 복수개의 신호들을 선택하는 멀티 스위치; 및상기 멀티스위치의 출력신호들을 증폭하는 다른 복수개의 IF증폭기들을 포함함을 특징으로 하는 LNB.
- 제1항에 있어서, 상기 LNA는복수개의 혼에서 수신된 수직편파와 수평편파를 동시에 수신함을 특징으로 하는 LNB.
- 삭제
- 제1항에 있어서, 상기 멀티스위치는SVR에서 LNB로 인가되는 전원의 DC전압의 레벨과 DC전압에 내포된 TONE신호의 유무를 검출하여 스위칭에 필요한 소정 비트의 디지털신호로 변환시켜주는 신호검출부; 및상기 신호검출부에서 만들어진 소정 비트의 디지털신호에 따라서 복수개의 위성으로부터 수신되는 수직편파와 수평편파 중 1채널의 신호만을 출력시켜주는 스위칭부를 구비함을 특징으로 하는 LNB.
- 삭제
