摘　　要：以非线性传输线(NLTLs)理论和孤子波理论为基础,仿真设计了一种非线性传输线梳状谱发生器。该梳状谱发生器由5段具有不同布拉格截止频率的NLTL级联而成。测试结果显示,该梳状谱发生器的10次谐波输出功率为4.2 dBm。本方法同传统方法相比,具有高次谐波输出功率大、电路结构简单、调试容易等优点。A comb generator is designed based the theory of harmonic generation of nonlinear transmission lines（NLTL）and the theory of soliton wave.To simulate the comb generator,the gradually scaled nonlinear transmission lines are used consisting of five segments which have different Bragg cutoff frequency.The test results show that the output power of tenth Harmonic is 4.2dBm.Compared to conventional ways of multiplier,this way has the advantages of bigger output power of higher harmonic,the sample circuit structure,debug easily,and so on.
