低功耗中频数字化子系统

AD9874是一款通用中频子系统，可对带宽最高至270 kHz的低电平10至300 MHz中频输入信号进行数字处理。AD9874的信号链包括一个低噪声放大器、混频器、一个带通Σ-Δ型模数转换器以及一个具有可编程抽取系数的抽取滤波器。自动增益控制(AGC)电路提供12 dB的连续增益调整。\n\n 高动态范围和带通Σ-Δ型转换器内在的抗混叠功能，使该器件能处理比目标信号强度高达95 dB的阻塞信号。除串行外设接口端口外，辅助模块还包括时钟和LO频率合成器。\n\n 通过SPI端口可对AD9874的许多参数进行编程，因此该器件可针对特定应用进行优化。可编程参数包括：频率合成器分 • 输入频率：10至300 MHz\n\n• 基带(I/Q)数字输出\n\n• 电源电压：2.7 V至3.6 V\n\n• 输出信号带宽：10至270 KHz\n\n• 单边带噪声系数（SSB NF）：8 dB;
