【应用】ASB高增益低功耗射频放大器ASL226用于车载导航系统,频段范围0.7-6GHz,采用SOT-363小封装
新能源汽车作为汽车行业发展的新赛道,其能源系统采用光伏、风力、水力等可持续发展的电力系统,一方面能源环保可持续可再生,减少传统燃油车的尾气排放,减缓国家石油进口压力;另一方面,新能源是全球能源发展的新趋势,新能源汽车还能实现错峰用电储电的高效利用,发展国家的用电储电电力系统。
与传统的燃油车相比,新能源汽车的电子器件集成度更高,更庞大的信息处理系统,未来往更高智能的自动驾驶方向发展,像作为汽车视觉感知的激光雷达、毫米波雷达和图像传感器等,也是近几年新能源汽车热门配备,其中车载导航系统是其中一个车辆实时定位通讯的重要应用,方便车辆的追踪,路线导航以及未来更智能的车联网自动驾驶数据融合。
以下是一个车载导航系统的基本结构:主要组成部分有接收天线、射频开关、LNA、滤波器、导航SOC、电源等。
车载导航系统由于车身结构机构受限,对体积和功耗要求较高,对于LNA的选型,这里推荐ASB品牌的高增益低功耗射频放大器ASL226,频段范围0.7-6GHz,是车载导航系统的理想选择。
ASL226具备以下优势:
1、高带宽,频段范围0.7-6GHz,支持GPS、伽利略、格洛纳斯等导航系统,以及T-DMB,CDMA,GSM,PCS,WCDMA,WiBro, WiMAX,andWLAN等无线系统;
2、高增益低噪声,两级结构LNA,在1575MHz下可提供28dB增益和1.1dB噪声系数,提供良好的射频性能;
3、超低功耗,低至5.5mA电流,减少系统功耗,满足供电系统长时间工作要求;
4、SOT-363小封装,外围电路只要5个部件,设计简单。
