简介:单端口输出的RFID读写模块往往不能满足客户想要多路天线端口输出的需求,而用电子开关实现多端口输出的方法不仅实现电路简单,也可以实现多路天线端口的输出(比如两路、四路、六路、八路等更多路天线端口)。这种多端口的读写模块更具市场竞争力。实现多路天线端口输出的方法一般有两种:第一种通过集成射频电子开关芯片实现;另一种则是通过分离器件二极管实现。前者占用布局面积小,实现简单,但对于四路以上的多端口,从印制电路板布局方面考虑不是很好布局;而分离器件二极管无论是几路天线端口布局都比较灵活方便,缺点就是可能占用PCB面积较大。因此一般情况下,两路或者四路的天线端口考虑用集成射频电子开关芯片方案,四路以上的考虑用分离二极管方案实现。下面从几个方面分析实现多路天线端口输出的方法以及所需注意的其它问题。
