ADI WiMAX解决方案

WiMAX (Superhet)

ADI的WiMAX解决方案基于直接上转换Tx通路，具有较低的元件数目、较少的毛刺，较少的滤波与较低功耗。Rx通路可以是IF采样或超外差基带I-Q采样架构。这些特性极适于灵活实现并可轻松运行在更高的RF频率。两个Rx信号链均专门为高敏感度、高线性应用设计，其固有的属性提供了极好的选择性。

If a large number of decoupling capacitors are used on the VDD line, re-applying power before VDD has discharged to 0 V can cause the AD7416/AD7417/AD7418 to reset into an unknown. state.
