文章介绍了一种基于雪崩二极管的太赫兹高次谐波混频器。雪崩击穿效应中的非线性特性能够引起高次谐波的频率变换效应。这种特性使雪崩二极管能够应用于毫米波及太赫兹频段的高次谐波混频。文章基于雪崩击穿效应中的非线性特性产生高次谐波的频率变换效应，提出将雪崩二极管应用于太赫兹频段的高次谐波混频，并从理论上分析高次谐波特性及其电路结构。16次谐波混频器获得了15dB的变频损耗，实验结果表明雪崩管高次谐波混频技术是一种极具应用价值的技术。

An investigation of Terahertz avalanche diode high order harmonic frequency mixer is presented. The nonlin-earity property of avalanche breakdown effect has evoked great interest in frequency conversion by high order harmonics, which is very benefit to realize millimeter and Terahertz wave high order harmonic frequency mixer. Based on the frequency conversion mechanism of high order harmonics generated in avalanche breakdown effect,the avalanche diode is applied in Terahertz wave high order harmonic frequency mixer. The theoretical analysis of high order harmonic character and the cir-cuit structure of frequency mixer are outlined. Experiment result of 15dB conversion loss is obtained by 16th harmonic fre-quency mixer based on avalanche diode,which demonstrate the satisfied performance of avalanche high order frequency mix-er.
