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 device to the test equipment. OTA is a kind of method connecting a device to a test equipment. There are roughly two kinds of connection method as shown below. One is Conductive and the other one is Radiative (or OTA). Simply put, OTA is a connection method via a......阅读全文
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.
