Abstract

본 발명은 C-band위성방송신호와 Ku-band위성방송신호를 1개의 피이드 혼으로 모두 수신할 수 있는 위성방송수신장치에 관한 것이다.The present invention relates to a satellite broadcasting receiver capable of receiving both a C-band satellite broadcast signal and a Ku-band satellite broadcast signal with one feed horn.

본 발명은 C-band위성방송신호와 Ku-band 위성방송신호를 수신하기 위하여 2개의 위성방송수신용 안테나와, 2개의 피이드 혼 및 2개의 저잡음 주파수변환기를 사용하므로 그 사이즈(size)가 커지고 원가가 상승하게 되는 문제점을 해결하기 위하여 1개의 피이드 혼으로 C-band 위성방송신호와 Ku-band 위성방송신호를 수신할 수는 위상방송수신장치를 제공하는데 그 목적이 있다.The present invention uses two satellite broadcasting antennas, two feed horns and two low-noise frequency converters to receive C-band satellite signals and Ku-band satellite signals. The purpose of the present invention is to provide a phase broadcast receiver capable of receiving C-band satellite signals and Ku-band satellite broadcast signals with one feed horn in order to solve the problem of rising.

본 발명은 안테나에 수신된 제1,2위성방송신호를 통과시키는 1개의 피이드 혼과, 동일방향으로 향하고, 제1,2위성방송신호를 각각 통과시키는 제1,2도파관과, 제1,2도파관사이에 형성되고 일측이 굴곡되는 매칭용 도파관과, 제1,2도파관을 통과하는 제1,2위성방송신호의 주파수를 각각 변환시키는 제1,2저잡음 주파수변환기를 포함하는 것을 특징으로 하고 1개의 피이드 혼과 동일방향으로 향하고 있는 좁은간격의 2개의 도파관을 이용하여 2개의 도파관에 각각 연결되는 저잡음 주파수변환기를 일체형으로 형성하여 크기를 작게하고 C-band 및 Ku-band 위성방송신호를 모두 수신할 수 있는 효과를 갖는다.The present invention provides a feed horn for passing first and second satellite broadcast signals received by an antenna, first and second waveguides facing the same direction and passing first and second satellite broadcast signals, respectively, and first and second. And a first and second low noise frequency converters, which are formed between the waveguides and have one side bent, and a first and second low noise frequency converters for converting frequencies of the first and second satellite broadcast signals passing through the first and second waveguides, respectively. Using two waveguides with narrow gaps facing the same direction as the two feed horns, a low noise frequency converter connected to the two waveguides is formed integrally to reduce the size and receive both C-band and Ku-band satellite broadcast signals. It has an effect that can be done.
