스마트 유틸리티 네트워크(SUN)용 무선전송 기술은 에너지 절약 지능형 그린 홈 네트워크 개발의 핵심 요소 기술일 뿐 아니라, 향후 ZigBee 기술을 대체하여 다양한 분야에 활용될 차세대 WPAN 기술이다. SUN 무선 전송 기술은 IEEE 802.15.4g SUN PHY-Layer 표준으로 지하나 반 지하 또는 복잡한 건물 주변과 같은 열악한 전파환경에서도 높은 링크 이득과 안정적인 전송속도의 제공이 가능한 비 면허 무선 전송기술이다[1][2][3]. 본 논문은 IEEE 802.15.4g SUN 표준을 만족시키는 RF 송수신기 칩 개발을 위해, RF 송수신기에 대한 시스템 단위 모의실험 환경을 구축하고, 시스템 설계에 필요한 설계 방법, 요구 사양 도출 및 시스템 예상 성능에 대한 내용이다. 또한 상기 시스템 단위 모의실험 결과를 바탕으로 실제 제작한 RF 송수신기 칩의 성능은 IEEE 802.15.4g SUN PHY-Layer 표준의 요구사양 보다 우수하였다.
