中频数字化子系统

AD9864是一款通用中频子系统，可对信号带宽范围为6.8 kHz至270 kHz的低电平10 MHz至300 MHz中频输入进行数字化处理。AD9864的信号链包括一个低噪声放大器(LNA)、一个混频器、一个带通Σ-Δ型模数转换器(ADC)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。辅助模块包括时钟和LO频率合成器。 AD9864的高动态范围和带通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。此特性可以降低中频滤波要求，从而降低无线电的成本，而且还支持不同通道带宽的多模无线电，使中频滤波器具 • 输入频率：10 MHz至300 MHz\n\n• 复合输出信号带宽：6.8 kHz至270 kHz\n\n• 单边带噪声系数（SSB NF）：7.5 dB\n\n• 输入三阶交调截点(IIP3)：−7.0 dBm \n\n• 无AGC范围最高达−34 dBm \n\n• 连续AGC范围：12 dB \n\n• 前端衰减器：16 dB;
