摘　　要：随着现代电子技术的飞速发展,人们对微波频率源提出了更高的要求,诸如频谱纯度、频率范围以及步进等要素都成为关注的重点。其中,相噪更是首当其冲地成为高性能频率源的重要标志之一。文章从具体的需求角度出发,对微波频率源的建设提出了对应的改进构想,并针对相应的构想对.相关相噪进行了估算。With the rapid development of modern electronic technology,people have put forward higher requirements for microwave frequency sources,and factors such as spectral purity.frequency range and stepping have become the focus of attention.Among them,phase noise is the first to become one of the im portant symbols of high-performance frequency sources.From the perspective of specific needs,this paper puts forward corresponding improvement ideas for the construction of microwave frequency sources,and estimates the relative phase noise for the corresponding ideas.
