摘　　要：为保证电路性能,在进行射频电路印制电路板(PCB)设计时应考虑电磁兼容性,这对于减小系统电磁信息辐射具有重要的意义。文中重点讨论按元器件的布局与布线原则来最大限度地实现电路的性能指标,达到抗干扰的设计目的。通过几个实验测试事例,分析了影响印制板抗干扰性能的几个不同因素,说明了印制板制作过程中应采取的实际的解决办法。EMC should be considered during the design of RF circuit＇s PCB to ensure the circuit performance and this is very important to decrease the electromagnetic radiation of the system. In this paper, how to in maximum realiae the circuit＇s specifications and anti-interference in line with the element layout and routing principles is discussed. Several factors affecting PCB anti-interference performance are analyzed through some experimental examples and practical solutions that should ber taken during PCB design are also brought out.
