一种改善频率源相位噪声性能的设计
A design for improving the phase noise performance of frequency source
摘要
Abstract
The signal generator is an important component of frequency source,under whose strong clutter conditions,low phase noise signals can improve the detection capability of small targets.In order to solve the tech-nical problem of lightweight and small volume of signal generators,a method is proposed to improve the phase noise performance by changing the frequency point and combination mode of the mixed frequency signal and adopting a cavity isolation design.Theoretical analysis and test results indicate that better phase noise perfor-mance can be achieved by using low-frequency signal mixing,that the design of cavity isolation helps enhance the isolation and anti-interference effect between modules effectively,and that the integrated design can reduce vol-ume and weight effectively.关键词
