【应用】国产高PSRR负输出线性稳压器用于毫米波雷达双电源运算放大器供电,宽电压输入范围-2.7~-24V
随着信息技术的发展,汽车行业也正在往智能辅助驾驶系统、自动驾驶系统等更高智能的应用领域方向发展。作为汽车智能驾驶的“眼睛”,光学传感器、激光传感器和毫米波雷达搭配使用,各有各自的优势,为智能安全驾驶保驾护航。
毫米波雷达作为一种采用非接触式的电磁波测距技术传感器,通过发射一定频率的电磁波,波长范围在1-10mm,来探测被测目标,并搜集反射回来的电磁波,由处理器进行数据处理,计算出电磁波的飞行时间,达到探测距离的测量。与其他测距传感器相比,毫米波雷达具有穿透能力强,可穿透烟、雾、灰尘等,具有全天候全天时的优势,且抗干扰能力也优于其他传感器,在防撞系统领域应用较广。以下是毫米波雷达的测距原理框图。
FPGA处理器上变频,输出中频信号,经ADC转为模拟信号,然后混频,产生高频电磁波,经功率放大器放大,由天线发射;接收端从天线经LNA、滤波器、混频,再通过ADC转为数字信号,给FPGA下变频处理,消除噪声干扰,分析信号的波形和相位,计算电磁波的飞行时间,得出测量距离。
运放作为毫米波雷达信号链路中信号调理的重要器件,精确性和稳定性要求较高,出于保障信号放大线性度的要求,往往采用双电源供电,双电源的总动态范围、输出电压/电流、精度、负载抗干扰性优于单电源运放。
对于运放双电源供电的负压供电解决方案,推荐圣邦微电子的SGM2209,宽电压-24V,-500mA低噪声,高PSRR负输出线性稳压器。
SGM2209用于毫米波雷达双电源运算放大器供电具备以下优势:
1、 宽电压输入范围从-2.7V到-24V,宽输出电压范围从-1.2V到-23V,可满足较高的负压电源需求,匹配灵活;
2、 具有高的PSRR、低噪声和良好的线和负载瞬态响应,非常适合对噪声敏感的电路设计;
3、 小封装尺寸,有绿色TDFN-2×2-6AL、TDFN-3×3-8L和SOT-23-5封装可选,适应较小的布板面积要求,节省空间;
4、 较宽的工作温度,范围为-40℃至+125℃,可耐受较高的恶劣工作温度环境。
