Design of a Wide-band Frequency Source Based on Quadrature Modulation Technique
Lin Qiao-li · Telecommunication Engineering · 2008
In view of the disadvanges of traditional DDS plug frequency synthesizer,a novel method for realizing the frequency synthesizer based on quadrature modulation technique is proposed.This method can easily realize the frequency source′s wide-band and high resolution output,and the circuit is simple.Finally,an example design based on this method is given,which provides an innovative idea for the design of frequency source with wideiband and high resolution.
