Abstract

In this paper, a Multi-Band Ku-band down converter was designed for reception of multi-band digital satellite broadcasting. The Multi-band low-nose down converter was designed to form four local oscillator frequencies (9.75, 10, 10.75 and 11.3GHz) representing a low phase noise due to VCO-PLL with respect to input signals of 10.7 to 12.75GHz and 3-stage low noise amplifier circuit by broadband noise matching, and to select an one band of intermediate frequency (IF) channels by digital control. The developed low-noise downconverter exhibited the full conversion gain of 64dB, and the noise figure of low-noise amplifier was 0.7dB, the P1dB of output signal 15dBm, and the phase noise -73dBc@100Hz at the band 1 carrier frequency of 9.75GHz. The low noise block downconverter (LNB) for receiving four-band digital satellite broadcasting designed in this paper can be used for satellite broadcasting of vessels navigating international waters.

본 논문에서는 범 세계적으로 이용가능한 다중대역 디지털 위성방송용 Ku-대역 하향변환기를 설계하였다. 설계된 다중대역 하향변환기는 광대역 잡음 정합에 의한 3단 저 잡음 증폭회로와 10.7~12.75GHz의 입력신호를 VCO-PLL에 의한 저 위상잡음을 나타내는 4개의 국부발진주파수(9.75, 10, 10.75 및 11.3GHz)를 형성하고 디지털 제어에 의하여 4개대역 중 하나의 IF 주파수 채널을 선택할 수 있도록 설계하였다. 개발한 저 잡음 하향 변환기의 전체 변환이득 64dB, 저 잡음 증폭기의 잡음지수는 0.7dB, 출력신호의 P1dB는 15dBm, band 1반송주파수 9.75GHz에서 위상잡음은 -73dBc@100Hz를 나타내었다. 설계한 다중대역 디지털 위성방송용 하향변환기(LNB)는 국제적으로 이동하는 선박 등의 위성방송용으로 사용가능하다.
