S波段下变频器的电磁辐射干扰产生及抑制

Generation and Suppression of Radiated EMI of S-Band Down-Converter

摘要: 基于ADI公司推出的HMC830频率合成芯片,设计了S微波段下变频器。针对HMC830本振输出的谐波干扰,给出了电磁辐射产生的原因及其改进措施。

Abstract: Based on the HMC830 integrated with frequency synthesizer,the S-band microwave down-converter is designed.Aiming at the harmonic interference of HMC830 local oscillator output,the causes of radiated EMI and its improvement measures are proposed.
