Abstract

This study is the analysis and verification process of the L-band satellite communications repeater thought PCB & circuit EM analysis. System performance can be vulnerable to various spurious inside the L-band satellite transponder, power conversion board, digital signal board, TM/TC board, such as control panels and blocks that are linked signal components when the winch is increased due to the noise component. So the whole system can cause performance degradation. PCB resonance analysis and EM simulation can be easily analyzed for a variety of optimal. Also, by setting the ports on the PCB, H/W designer wants to can easily analyze system.

본 연구는 위성통신 중계기의 L대역변환반의 PCB EM 분석을 하고, 불요파에 대한 취약 부분에 대해 최적화하였다. 위성중계기 안에는 L대역변환반 뿐만 아니라 전원반, 디지털신호처리반, TM/TC 제어반 등 다양한 기능 및 블록이 연동될 때 윈치 않는 신호 성분으로 인해 잡음성분이 증가되어 전체 시스템 성능 저하를 야기 시킬 수 있다. EM 시뮬레이션 툴을 사용한 PCB 공진해석은 보드 상에서 공진에 취약할 수 있는 부분에 대해 쉽게 분석을 할 수 있고, 다양한 시뮬레이션을 통해 최적의 설계를 할 수 있다. 또한 PCB에 포트를 설정하여 원하는 블록을 쉽게 분석할 수 있는 장점이 있다.
