无线通信 直放站中的自动电平那个控制ALC
ALC(Automatic level control自动电平控制)是直放站系统中极为重要的一环,它是指当放大器输出信号电平到达ALC设定值时,增加输入信号电平,放大器对输出信号电平的控制能力。
无线通信 UHF读写器设计中的FM0解码技术
 
 针对UHF读写器设计中,在符合EPC Gen2标准的情况下,对标签返回的高速数据进行正确解码以达到正确读取标签的要求,提出了一种新的在ARM平台下采用边沿捕获统计定时器数判断数据的方法,并对FM0编码进行解码。与传统的使用定时器定时采样高低电平的FM0解码方法相比,该解码方法可以减少定时器定时误差累积的影 ...

可编程逻辑 PCB Design Considerations and Guidelines for 0.4mm and 0.5mm WLPs
Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsidera ...
