中文摘要: 直接数字合成(DDS)是近年发展非常迅速的一种新型合成技术,有频率分辨率高,转换时间短等特点,与锁相合成技术(PLL)配合,可以设计出频带宽、分辨率高的频率合成器.介绍了DDS的基本原理及DDS+PLL的基本实现方法,设计了一种特高频率、宽频带、小步进的频率合成器.

中文关键词: 直接数字合成锁相合成混频频率合成器

Abstract:The direct digital synthesis (DDS) is a new kind of synthesis technology which has developed quickly in recent years. It has the advantages of high frequency resolution and short tuning time. Combined with phase locked loop (PLL), a wide band, high resolution's frequency synthesizer can be designed. This paper introduces the basic theory of DDS and the method to achieve DDS+PLL, presenting an example of designing a high frequency, wide band, small step's frequency synthesizer.

keywords: DDS PLL mix frequency frequency synthesize
