摘要
复杂频率源系统,其参考信号需要进行多路功分处理,该处理会对参考信号的相位噪声产生影响。文章针对参考信号功分放大带来的相位噪声恶化现象,给予了详细的理论分析,并结合实例,给出适合工程需要的解决方法,工程实践中验证了该方法的有效性。
In the complex frequency synthesizer design,the reference signal needs to be divided into several channels,which cause the phase noise of the reference signal degraded.A detailed theoretical analysis of the problem is presented in this paper,and a solution is given,which has been verified in engineering practice.
