S波段频率合成源的研制

Preparation of S-band frequency synthesizer

介绍了直接数字合成(DDS)与锁相环路(PLL)的基本原理及利用DDS与PLL相结合的方法设计的频率合成源,并给出了该频率合成源的实例和达到的性能指标。

The basic principles of direct digital synthesizers(DDS)and phase-locked loop (PLL )are introduced in this paper. An experiment model for frequency synthesizer by the way of combining DDS with PLL is given, and the performance index for the synthesizer is also given.
