Synthesizers direct digital synthesis (DDS) techniques allow digital signals to form the desired shape and frequency, the stability of which is determined by specifying a quartz reference oscillator. Now they are increasingly being used, particularly in modern phased antenna arrays. The study of the spectral and phase characteristics of shapers based on the DDS in the formation of microwave signals and the subject of this article.
