在RF电路设计中,常常会遇到数字电路对RF电路干扰严重、供电电源噪声干扰比较突出、一些不合理电路地线的存在、天线对RF电路的辐射干扰等问题。对此,笔者结合实际,分析其原因,探讨了RF电路设计的基本原则,并提出了选择可靠的地线层面、RF电路设计的去耦处理、RF电路电源的星形布线和屏蔽RF电路信号的影响等对策措施。
In the design of RF circuits, digital circuits often encounter serious interference to the RF circuit, power supply noise interference is more prominent, the existence of some unreasonable circuit ground, the antenna on the RF circuit radiation interference and other issues. In this connection, the author analyzed the reasons and discussed the basic principles of RF circuit design, and proposed the choice of reliable ground plane, RF circuit design decoupling processing, RF circuit power supply of the star wiring and shielding RF circuit signals The impact of measures such as countermeasures.
