Design of an IF Sampling Module and its Applications in the Digital Receivers

摘要:

基于AD6644设计了一个中频采样模块，分别用于一种脉冲编码调制／调频遥测数字接收机和一种宽带雷达数字接收机中，实验结果证明两种数字接收机均能正确地解调信号，达到了预定指标。

Abstract:

An IF sampling module based on AD6644 has been designed,which is applied in a PCM/FM telemetry digital receiver and in a wideband radar digital receiver respectively.Experimental results indicate that both receivers can demodulate signals correctly,and re
