Abstract

본 발명은 위성방송을 수신하는 LNB의 발진주파수 설정방법에 관한 것으로 수직 및 수평 신호를 편파로 받아 처리하는 위성방송 수신용 LNB에 제1저잡음증폭기(31a)의 수직신호 입력은 11.2-11.45GHz로 하고, 제2 저잡음 증폭기(31b)의 수평신호 입력은 10.95-11.7GHz로 하며, 대역통과된 상기 제1 및 제2 저잡음 증폭기의 출력 신호와 발진신호를 제1 및 제2 혼합기(33)(35)에서 혼합시 수직신호용 발진기(34)의 발진주파수는 10.26GHz로 하고, 수평신호용 발진기(36)의 발진주파수는 9.64GHz로 하며, 상기 혼합된 수직 및 수평신호를 증폭시키고 필터링시켜 결합시킨 다음 수직신호는 940-1190 MHz로 수평신호는 1310~2060 MHz로 각각 출력하도록 한 것이다.The present invention relates to a method for setting the oscillation frequency of an LNB for receiving satellite broadcast signals. The horizontal signal input of the second low noise amplifier 31b is set to 10.95-11.7 GHz, and the first and second mixers 33 and 35 output the output signals and the oscillation signals of the first and second low noise amplifiers that have been passed through. Oscillation frequency of the oscillator 34 for the vertical signal is 10.26GHz, oscillation frequency of the oscillator 36 for the horizontal signal is 9.64GHz, and amplifies, filters and combines the mixed vertical and horizontal signals. The signal is output at 940-1190 MHz and the horizontal signal at 1310-2060 MHz.
