| 摘 要： | 提出了一种新的频率合成方法，该方法的基本思想是，按照一种特定算法，对于每一个所需的输出频率，对数字锁相环的可程控反馈分频器设置一组不同的分频系数，以使环路鉴相器输出端干扰的频率与频率分辨率相互独立，从而便可同时获得高的频率分辨率和较大的环路带度。

| Abstract: | A new frequency synthesis method is presented in this paper. Its fundamental ideology is that for any frequency needed to be output,the controller sends a different group of dividing numbers to the feedback programmable divider of PLL by means of a special algorithm so as to make the interference frequency at the output of the phase detector and the frequency resolution indeqendent from each other. Therefore,high resolution and wide bandwidth are achieved simultaneously. |
