【应用】嘉康电子介质滤波器用于三频mesh的Wifi 6E设备中

时间： 2021-07-18 来源：世强

技术问答

Wifi网络作为最主流的小范围局域数据传输的网络，一直以来，其2.4G的传输和覆盖效果不佳都是问题，现在随着网络里面数据流量的大幅增加，其传输频率更是扩展到5G乃至6G。即便如此，在某些热点区域，仍然存在流量过大，导致拥堵的问题。因此，WIFI 6E设备越来越多的采用mesh组网的方式来优化信号的传输和覆盖。

Mesh组网的优点在于如果最近的AP流量过大，那么数据可以自动再路由到一个通信流量较小的邻近节点进行传输。由于Mesh网络中每个节点的传输距离短，无需过分担心辐射的问题；节点间的通讯采用专有的无线频段（通常是5GHz）而非传统的信号中继， Mesh除了具有抗干扰、信道利用率高的特点外，还能最大限度的降低带宽的损耗，有效弥补上述的短板，堪称是多楼层无线覆盖黑科技。在实际应用中，WIFI 6E可采用2.4+5G+6G 即2.4+5492+6525的方式，既考虑覆盖，又兼顾传输速率。其可能的频带分布如下图。

嘉康电子的介质滤波器很好地解决了5Gwifi与6Gwifi之间的高隔离度要求，带外抑制达到45dB以上（大部分频段满足50dB）。在5G频段的DFS0407R5492P685B1-R1和6G频段的DFS0406R6525P1200B1-R1性能如下，45dB以上的带外信号衰减可很好的解决相邻频段的信号干扰。
