Why testing in Far Field ? Probably by now, you may have a question 'Why do we need to test in Far Field ?'. It would not be easy to get a direct answer to this question. So let me change the question a little bit. Why we do not test in Near field ?The simple answer to this question is that the measurement result in this region tend to be unpredictable and subject to change with small c......阅读全文
OTA (Over The Air) OTA stands for Over The Air. In order to perform test a device with any test equipment, you need a way of connecting the d
因此对前端模块（PA和LNA）、双工器、混频器和滤波器等RF通信组件进行特性分析将面临着一系列新的测量挑战。为在较大带宽下实现更高的能效和线性度，5G PA引入了数字预失真（DPD） 等线性化技术。由于电路模型难以预测记忆效应，因此降低记忆效应唯一有效方法是测试PA并在时域信号通过D
< Figure 6 - Antenna Dimensions for various configuration > There is another reason why defining D gets difficult.
