title="GPS">GPS" title="GPS">GPS" title="GPS">GPS信号的线性度、噪声系数以及GPS（包括GLONASS和伽利略卫星定位系统）的接收效果，同时继续保持恩智浦在此类产品市场上的体积最小。恩智浦BGU700x系列作为业界首款可以动态抑制手机、蓝牙及WLAN过强发射信号的GPS LNA产品，保证了微弱的GPS信号能够得到最佳的接收效果，在-40至 -20 dBm干扰环境下能将信号提高10 dB或者提供更好的IP3，同时将噪声系数控制在1 dB以下。BGU700x LNA产品仅需两个外部元件，节省50%的PCB面积和10%的器件成本。

　　恩智浦开云棋牌官网在线客服产品市场经理Duco Das表示，“消费者对于GPS接收效果的要求与日俱增，这就使得GPS接收效果朝着首次定位时间更短，定位精度更高的方向推进。而我们最新的LNA产品能提供完整可靠的IC解决方案，全面提高GPS性能，阻止其他干扰信号进入器件。LNA可以根据信号输入状况动态调节设备的接收，传输更多所需的频率信号，同时最大可能地保持GPS信号处于连通状态。对于寻求分立解决方案改善GPS接收的设计人员来说，我们的新型LNA系列无疑是理想的首选。”

　　GPS 作为标准功能配置被广泛应用于各种消费产品，如个人导航设备、数字摄像机、手表、电动汽车等。GPS信号的功率水平相对较弱，低于-155 dBm的底噪。很多消费产品，特别是智能手机，其中的蓝牙、WLAN及蜂窝单元等强发射器会驱使GPS LNA进入饱和状态。GPS LNA在饱和状态下，增益会降低，结果造成GPS接收不良；同时在发射机信号中还会形成互调与谐波，抑制微弱信号，导致GPS接收失灵。

　　恩智浦BGU700x/BGU8007系列采用自适应偏置技术，能够实时检测到任何干扰源的输出信号，通过临时增大电流对GPS信号进行补偿。从而始终保持最佳的GPS信号接收状态。BGU700x/BGU8007系列中的每款器件只需一个输入匹配电感和一个供电去耦电容。这种设计非常紧凑，而且节省了大量材料。例如，BGU7005采用1.45 x 1 mm封装，应用面积仅需4.53 mm2。与9.06 mm2应用面积的方案相比，减少了50%。新款LNA还提供极小型6管脚封装，可减小面积、降低成本并且改善接收效果，适用于有源天线或贴片天线系统。

　　主要特性：
　　•低噪声：0.75 dB
　　•系统优化增益：16.5或19 dB
　　•符合AEC-Q100 标准（BGU7004、BGU7008），在恶劣条件下保证最高可靠性
　　•小型、6管脚无引脚封装1.45 x 1.0 x 0.5 mm
