北斗B1/GPS L1雙模雙通道射頻導航芯片

RX3007 是一款高度集成的 GPS L1/BD B1 無線解決方案，支持雙通道同時工作。片上集成了低噪聲放大器，鏡頻抑制混頻器，自動增益控制電路，帶通濾波器，中頻放大器，壓控振蕩器，小數(shù)分頻鎖相環(huán)，模數(shù)變換器和低壓差線性穩(wěn)壓器（LDO）等電路。從天線進來的射頻信號，經過下變頻、放大和模數(shù)轉換后分成兩路數(shù)字中頻信號輸出給基帶芯片。兩個通道共用接收天線和前端低噪聲放大器（LNA）電路，射頻信號通過片外聲表濾波器濾除頻譜以外的雜散干擾后，分成兩路經過兩個混頻器（Mixer），中頻帶通濾波器（BPF）濾波，可變增益放大器（AGC）和 2bit 模數(shù)變換器（ADC）電路，量化成數(shù)字信號輸出給基帶芯片
