【应用】AST20S-A汽车级LNA用于Tbox,噪声系数仅0.5dB、增益18dB,频段可覆盖所有卫星定位频段
Tbox功能强大,集成多种通信模块,导航定位模块是非常重要的一个功能,但用于射频前端的LNA,很少有汽车级且能够满足多种定位频段的产品,ASB公司的AST20S-A汽车级LNA是一款性能不错的产品,同时支持GPS的L1/L2/L5频段,在RTK定位时,能够达到更高的定位精度。
定位精度一般取决于定位模块能够接收到的符合信号质量的卫星信号的卫星数量,主要相关指标是信噪比、信号强度及信号频段。多数支持多频的定位模块很少内置射频放大器,这就需要在定位模块与天线之间增加有源部分,提高信号质量,高性能的LNA必不可少。AST20S-A汽车级LNA的噪声系数只有0.5dB,增益18dB,频段可覆盖所有卫星定位频段,其在常用的GPS的L1/L2/L5频段,性能更好,可以同时支持。
应用在1164~1620MHz频段的匹配电路如下图所示
为了保证最优的性能,采用严格的匹配是必要的,其在1164~1620MHz频段的性能表现如下图所示
作为通过AEC-Q100认证的汽车级产品,其工作温度范围同样满足与工业应用,-40~+85℃应用完全没有问题,特别是特种定位终端,是不错的选择。应用于汽车Tbox或其他定位终端,能大幅度提高定位精度,提高性能。
