Abstract

위성방송 수신용 더블 LNB의 채널 확장을 위한 와이어 밴드화는 제1 LNA를 거친 수평판파 RF입력신호는 10GHz로 설계된 제1 OSC의 출력으로 믹싱하여 그 IF 신호가 950-1700MHz로 설계된 제1 BPF를 통과하게 구성하고, 제2 LNA를 거친 수직편파 RF입력신호는 9.1GHz로 설계된 제2 OSC의 출력으로 믹싱하여 그 IF신호가 1700-2600MHz로 설계도니 제2 BPF를 통과하게 구성하고, 상기 제1, 2BPF를 거친 수행 IF 및 수직 IF는 공통 IF앰프를 거쳐 950-2600MHz의 IF신호로 출력되게 구성하는 것을 통하여 구현시킨다.The wire bandization for channel expansion of the double LNB for satellite broadcasting is performed by mixing the horizontal slate RF input signal passing through the first LNA to the output of the first OSC designed at 10 GHz, and the IF signal having the first BPF designed at 950-1700 MHz. And the vertically polarized RF input signal passing through the second LNA is mixed with the output of the second OSC designed for 9.1 GHz, and the IF signal passes through the second BPF at 1700-2600 MHz. The performance IF and vertical IF which passed through 1 and 2BPF are implemented by configuring the output IF as a 950-2600MHz IF signal through a common IF amplifier.

Claims

In the double LNB for satellite broadcasting reception, the horizontal plate wave RF input signal passing through the first LNA is mixed to the output of the first OSC designed for 10 GHz, and the IF signal passes through the first BPF designed for 950-1700 MHz, The vertically polarized RF input signal passing through the second LNA is mixed with the output of the second OSC designed at 9.1 GHz so that the IF signal passes through the second BPF designed at 1700-2600 MHz, and the horizontal IF passed through the first and second BPF. And a vertical IF is configured to be output as an LNB IF signal of 950-2600MHz through a common IF amplifier.
