摘　　要：设计了基于容性肖特基二极管的220GHz非平衡三倍频器。首先对容性肖特基二极管进行测试和关键参数提取,建立了肖特基二极管的等效电路模型,以此为基础进行三倍频电路设计;在倍频电路设计中通过引入紧凑悬置微带谐振单元(CSMRC)滤波结构来减小信号传输损耗;由于三倍频电路设计中难以实现全波阻抗匹配,因此采用了整体电路结构谐波平衡调匹配方法设计倍频电路,最后对制备出的倍频器进行测试和分析;实验测试结果表明:倍频器在213.1~221.6GHz范围内输出功率大于10 mW,倍频效率大于5%,最高输出功率为18.7mW@218.6GHz,最高倍频效率为8.24%@217.9GHz。A 220 GHz unbalanced tripler based on Schottky varactors was designed. The Schottky varactors were measured to extract parameters for modeling Schottky diodes. A lump equivalent circuit model of Schottky diode was established for 220 GHz tripler circuits design. To reduce the signal transmission loss, a compact suspended microstrip resonator cell （CSMRC） filter structure was introduced to reduce low pass filter circuit length. Since it was difficult to achieve fuII-wave impedance matching in 220 GHz tripler circuit design, we adopted a method of adjusting impedance matching in overall circuit structure harmonic balance simulation to design a 220 GHz tripler circuit. Finally, the designed 220 GHz tripler was measured and discussed. The experiment shows the output power and efficiency between 213. 1 GHz and 221. 6 GHz are above 10 mW and 5%, respectively. The maximum oatpat power is 18. 7 mW at 218.6 ,GHz and the maximum cfficicncy is 8.2% at 217.9 GHz.
