2.5GHz、45dB、RF检测控制器

MAX4000/MAX4001/MAX4002是一组低价格，低功耗的对数放大器，被设计用于控制运行于0.1GHz至2.5GHz频率范围的RF功率放大器(PA)。45dB的典型动态范围使得这组对数放大器能够适用于多种无线设备，包括蜂窝式手机的PA控制，发射机的功率测量以及终端设备的RSSI。相比基于二极管检波器的方案，对数放大器具有宽得多的测量范围和更高的精确度。这组器件在整个工作温度范围内(-40°C至+85°C)具有优异的温度稳定性。\n\n 这个系列的器件提供三种不同的输入电压范围供设计者选择，无需外加衰减器，简化了PA控制环的设计。这些对数放大器是电压测量器件，典型信号范围分别 • 完整的RF检测PA控制器\n• 多种输入范围\n• MAX4000：-58dBV至-13dBV (50Ω时，-45dBm至0dBm)\n• MAX4001：-48dBV至-3dBV (50Ω时，-35dBm至+10dBm)\n• MAX4002：-43dBV至+2dBV (50Ω时，-30dBm至+15dBm)\n\n\n• 频率范围：100MHz至2.5GHz\n• 线性dB响应具有温度稳定性\n• 响应快速：10dB阶跃70ns\n• 输出驱动能力10mA\n• 低功耗：3V电源时17mW (典型)\n• 关断电流30µA (最大)\n• 提供8焊球UCSP和细小的8引脚µMAX封装;
