摘要
射频光纤系统采用光纤技术对射频信号进行处理，具有带宽大、损耗低、体积小、重量轻等优点。当输入信号功率足够大时，系统会由于非线性效应产生新的频率分量。文章从数学上分析了射频光纤系统的非线性特性，给出了相应理论分析和实验结果，为进一步研究非线性特性提供了一定的基础。
Optical fiber technique can be used for processing signals in RF system. There are many benefits of optical fiber system, including wide bandwith, low loss, small volume, light weight. When input power arrives to a great extent, some new frequency signals can be pro- duced because of nonlinear effect. In this paper, nonlinear characteristics of RF fiber process- ing system are investigated, and results in theory and experiment are demonstrated.
