摘要
分析了影响飞机上某电台接收频段的噪声源和耦合路径，然后针对产生干扰源的设备，在其内部加入铁氧体磁珠和扩谱芯片，利用铁氧体磁珠优良的吸收电源的高频干扰特性和扩谱芯片可以有效地将干扰频谱上的高频能量尖峰削低的特性，有效地解决了机上电台接收频段易被干扰的问题。
Through the analysis of the interference source and the coupling way that affect the receiving frequency band of some airborne station,the equipment causing interference is located. Spread-Spectrum chip that can effectively reduce radiated emissions by depressing spectrum peaks and magnetic bead that can well absorb the high frequency interence energy of power supply are installed in the interference equipment,that effectively solve the problem of the airborne station disturbed.
