EMI Suppression and EMC Analysis of RF Circuits

该文重点分析了射频电路EMI电磁干扰的三大要素和EMC设计方法,采用了滤波、屏蔽和短接地综合处理与抑制方法,有效降低了EMI杂散干扰信号,将原来典型频点杂散信号幅度降低到噪声电平以下,明显改善了电路的信号质量,且增强了射频电路的抗骚扰能力,充分验证了该综合处理抑制方法对射频电路EMC设计和EMI抑制设计具有重要意义和实用价值。

This paper focuses on the analysis of three major elements of Electro Magnetic Interference EMI RF circuit and EMC design method,using filtering,shielding and grounding short comprehensive treatment and suppression methods,effectively reduce the EMI spurious interference signal,the original typical frequency spurious signals to reduce the noise level to,obviously improve the quality of the signal circuit,and enhances the anti-jamming ability of the RF circuit,and fully proved that the inhibition of comprehensive treatment method has important significance and practical value for EMC RF circuit design and EMI control design.
