Abstract

This paper describes the design and fabrication of a BUC(Block Up-converter) which is a component of a FST (Flyaway Satellite Terminal), one of the ET(Earth Terminal) of the military satellite. BUC is physically composed of an up-converter module, a high power amplifier module, a receive band suppression filter, a housing, and a cable assembly. It was designed using simulator AWR to satisfy the electrical characteristics of BUC's such as maximum output power, gain, unwanted signal, and intermodulation. The maximum output power and gain characteristics were measured at 43.4dBm and 51.8dB, respectively. The unwanted wave and intermodulation characteristics were -73.5dBc and -31.9dBc, respectively. Of the electrical requirements of Table 1, not only the above four but also all of the items were confirmed to be satisfied.

본 논문은 군 위성의 지상 단말 중 하나인 운반형 위성단말의 구성품인 고출력상향주파수변환기의 설계 및 제작에 관해 기술하였다. 고출력상향주파수변환기는 물리적으로 상향변환모듈, 고출력증폭모듈, 수신대역억제필터, 기구, 케이블조립체로 구성된다. 고출력상향주파수변환기의 전기적 요구 규격인 최대 출력 전력, 이득, 불요파, 상호변조 등의 전기적 특성을 만족하기 시뮬레이터(AWR)를 이용하여 설계하였다. 최대 출력 전력, 이득 특성은 각각 43.4dBm 및 51.8dB로 측정되었고, 불요파, 상호변조 특성은 각각 -73.5dBc 및 -31.9dBc로 측정되었다. 표 1의 전기적 요구 사항 중 상기 4가지 뿐만 아니라 다른 항목에 대해서도 모두 만족함을 확인하였다.
