摘要
文中首先介绍DDS技术的基本原理,然后介绍AD公司的一款高性能DDS芯片AD9858的应用,最后将AD9858与可编程门阵列(FPGA)相结合,设计了一种低杂散,低相位噪声,灵活可变的雷达信号源发生器,本文详细阐述了该系统的设计方案和工程实现。
The basic principle of DDS technique is firstly introduced, and then the application of a high performance DDS chip AD9858 produced by Analog Device Inc is presented; and finally, a flexible and variable signal generator with low stray and low phase noise is designed by combining AD9858 and FPGA. Its design scheme and project implementation in engineering are described in detail.
