摘要
文中在简要叙述锁相环的基本原理的基础上,介绍了ADF4218L的主要特点及基于ADF4218L锁相频率合成器硬件电路的设计和实现。在此基础上讨论了实际电路调试中应该注意的问题并给出了输出信号频谱。
At the beginning the principle of PLL is introduced, then a hardware design and implementation of frequency synthesizer based on ADF4218L is presented. In the end, we discuss several problems that we should take care in circuit debug. We also display spectrum of output signals.
