【经验】如何测试Silicon Labs蓝牙AoA基站天线阵列板BRD4191A的射频性能
SILICON LABS提供的蓝牙AoA室内定位方案，包括基站端和标签端这两部分，而基站端这部分，Silicon Labs提供完整的PCB设计图，硬件方面无须自己再进行设计，但是不少开发者按照Silicon Labs的制板要求进行制板后，测试出来的效果并不是很好，想改善但是却不知道如何对板子进行测试，本文接下去将以天线阵列板BRD4191为例，介绍如何测试Silicon Labs的蓝牙AoA基站天线阵列板。
1、测试天线阵列板性能，总共需要测试两个点，一个是靠近芯片端的那一部分，接下去我们称为A点，另一个是天线阵列的各个天线，我们只需要测试16个天线中的一个就行了，接下去我们称为B点。
2、测试A点的话，需要将板子上的R1去掉，然后把R2接上，接着通过板子预留的IPEX座测试这部分电路的阻抗等性能。
3、测试B点的话，需要在同一天线的两个过孔中的一个，将其与射频开关芯片的链路割断，然后在接近过孔的地方选择一块地，将其刮开露出铜，将同轴线的信号接到过孔上，地接到露出的铜上，接着就可以测试天线部分的阻抗等性能了。
