Abstract

This study describes the design and implementation of IFA(Input Filter Assembly) for Digital Satellite Communication. The IFA unit for SHF band consists of coupler, LPF(Low Pass Filter) and input Filter. Through the pre-simulation analysis of space environment, the possibility of the malfunction of equipment minimized and we designed a reliable IFA through simulation for vibration analysis generated during the launch, and compared pre-simulation of main performance results to test results about main performances of IFA after production.

본 연구는 디지털위성중계기용 SHF 대역 IFA(: Input Filter Assembly)의 설계 및 구현에 대해 기술하였다. SHF 대역 입력필터조립체는 Coupler + LPF(: Low Pass Filter) 및 입력필터로 구성된다. 제작 전 우주환경에 대한 사전 시뮬레이션 분석을 통하여 장비 오동작 가능성을 최소하였으며, 발사환경 시 발생하는 진동에 대한 시뮬레이션을 통해 신뢰성 있는 IFA를 설계하였으며, 제작 후 주요 성능지표에 대해 만족여부 확인 및 사전 성능 시뮬레이션 결과와 비교하였다.
