摘要
Abstract
The structure and principles of direct digital synthesizer（DDS） are introduced,and key technologies of DDS are introduced into the frequency source.A low noise frequency source based on MCU＋new DDS device is designed with a range of frequency of 46.5~75 MHz.Some relevant tests are carried out after the frequency source circuit finished.Experiments show that the frequency synthesizer has the features of precise resolution and low phase turning noise.关键词
