摘　　要：非线性传输线通常用来实现谐波产生和脉冲形成。利用左手非线性传输线的谐波产生特性,设计仿真了100 MHz的三倍频器。该倍频器采用5级级联的"T"形非线性单元,不需要任何偏置电路。相比传统方法,该方法具有电路尺寸小、结构简单、调试容易、倍频效率高、相对带宽较宽等优点。Nonlinear transmission lines are used extensively for harmonic generation and pulse shaping. This paper utilizes the character of harmonic generation of left-handed nonlinear transmission line, designs and simulates 100 MHz tripler. This tripler adopts the free cascaded T-shaped nonlinear units, resulting in the absence of a biasing circuit. Compared with traditional methods, this method has the advantages of circuit of small size, simple structure, easy debug, higher efficiency of frequency multiplication, wider rehtive bandwidth, and so on.
