射频电路PCB在教学中的设计

Radio Frequency Circuit PCB Design in Teaching

手持无线射频电路技术随着通信技术的发展被广泛运用,其中射频电路的性能指标直接影响整个产品的质量。如何减少辐射能力、如何提高抗干扰能力是设计射频电路PCB的关键。本文通过多年的教学实践总结,以Pro-tel99 SE软件进行掌上产品的射频电路PCB设计为例,通过科学的结构设计、布局与布线有利于提高RF(射频)电路PCB设计的可靠性,既能防止和抑制EMI(电磁干扰),又能达到电磁兼容的要求。

With the development of communication technology,the RF-circuit technology of handheld wireless has been widely used,one of the performance index had affected directly the quality of the products.In PCB designs,the main factor is how to reduce radiation ability and how to improve anti-jamming ability.This paper summarized teaching practice in palm Protel99 SE software for many years.In PCB design reliability,for example,through scientific design,layout and wiring,this method is not only to prevent EMI but also maintain of electromagnetic compatibility.
