adf传感器:车ADAS雷达、微波雷达传感器和工业雷达系统的常用芯片ADF5904ACPZ

ADF5904是一款高度集成的4通道、24 GHz接收机下变频器MMIC,具有业界卓越的低噪声性能、高线性度和低功耗组合。ADF5904集成式多通道接收机下变频器具有10 dB噪声系数性能,优于竞争型对手器件3 dB。该器件功耗低50%,采用小型、性价比高的5 mm × 5 mm LFCSP塑料封装。该器件的四个片内接收通道采用简单的单端连接与四个独立天线相连,从而简化了射频传输线设计和PCB布局布线,同时缩小了电路板尺寸。接收机下变频器可同时直接放大并转换4路24 GHz接收机信号,以产生高质量、高幅度基带信号或降低频率信号,以便轻松连接ADI 4通道模数转换器或模拟前端(AFE)。ADF5904 还提供集成式温度传感器,无需使用分立式检测元件;这些元件原本可能需要在系统装配和测试期间占用额外的时间与资源来校准。
ADF5904针对采用数字波束成形的多通道接收机高频应用设计,如汽车ADAS雷达、微波雷达传感器和工业雷达系统;在这些应用中,能效正在成为越来越重要的系统级设计考虑因素。ADF5904 24 GHz接收机具有同类一流的接收机灵敏度,相比竞争型RF IC技术整体功耗更低,因而适合此类应用以及其他传感器应用。
ADF5904ACPZ主要特性4个接收通道,接收机通道增益:22 dB噪声系数:10 dB,P1dB:–10 dBm功耗:0.5 mW(全部4个通道开启)LO输入范围:-8 dBm至+5 dBm接收机至IF隔离:30 dBRF信号带宽:250 MHz模拟输出的片内温度传感器:±5°adf传感器:半导体传感器ADF4113BRUZ中文规格书  第1张
