摘要

摘要: 设计了基于容性肖特基二极管的220 GHz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213.1~221.6 GHz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18.7 mW@218.6 GHz，最高倍频效率为8.24%@217.9 GHz。

Abstract: 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 full-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 output power is 18.7 mW at 218.6 GHz and the maximum efficiency is 8.24% at 217.9 GHz.
