Abstract： With the rapid development of modern electronic technology，people have put forwardhigher requirements for microwave frequency sources，and factors such as spectral purity，frequencyrange and stepping have become the focus of attention.Among them，phase noise is the first tobecome one of the important symbols of high-performance frequency sources.From the perspective ofspecific needs，this paper puts forward corresponding improvement ideas for the construction ofmicrowave frequency sources，and estimates the relative phase noise for the corresponding ideas.Key words ： microwave，frequency source，implementation scheme，phase noise
