北斗B1/GPS L1双模双通道射频导航芯片

RX3007 是一款高度集成的 GPS L1/BD B1 无线解决方案，支持双通道同时工作。片上集成了低噪声放大器，镜频抑制混频器，自动增益控制电路，带通滤波器，中频放大器，压控振荡器，小数分频锁相环，模数变换器和低压差线性稳压器（LDO）等电路。从天线进来的射频信号，经过下变频、放大和模数转换后分成两路数字中频信号输出给基带芯片。两个通道共用接收天线和前端低噪声放大器（LNA）电路，射频信号通过片外声表滤波器滤除频谱以外的杂散干扰后，分成两路经过两个混频器（Mixer），中频带通滤波器（BPF）滤波，可变增益放大器（AGC）和 2bit 模数变换器（ADC）电路，量化成数字信号输出给基带芯片
