卫星射频接收机电磁兼容防护设计方法

射频接收机是卫星测控、导航、有效载荷等分系统的重要组成设备,也是对电磁干扰最为敏感的设备,在对卫星进行电磁兼容性（EMC）设计时,必须充分考虑射频接收机的EMC防护,以保证其在卫星电测、发射和在轨运行时能够在其所处电磁环境中正常工作.文章描述了卫星射频接收机典型的EMC防护设计方法,从屏蔽、电磁泄露防护和天线耦合防护等方面进行了阐述.

EMC Protection Design for RF Receiver of Satellite

RF receiver is a critical equipment of TI＆C, navigation and payload subsystems of satellites, and it is much sensitive to EMI. EMC protection of RF receiver must be taken into satellite EMC design in order to ensure its normal operation during testing, launching and in - orbit operating of satellites. This article describes typical EMC protection design techniques of RF receiver, including shielding, electromagnetic leakage and antenna coupling mitigation.
