| 摘 要： | 针对亚毫米波频段混频二极管管对模型获取困难的问题,提出了利用全波电磁场分析算法提取管对无源结构参数,并与管对直流电流-电压特性参数结合获取混合电路等效模型的建模方法.分析了谐波混频器原理,设计并实现了一个工作于2mm波段的二次谐波混频器.测试结果显示在116～120GHz频率范围内,其变频损耗小于20dB,与仿真数据基本吻合,证明本文提出的混合电路建模方法及所提取模型的有效性.

| Abstract: | A method for designing the submillimeter wave sub-harmonically pumped mixer based on a hybrid circuit model is presented in this article.To resolve the difficulty of extracting the Schottky diode pair's model for submillimeter wave band mixer,a full wave electromagnetic analysis was implemented to extract the passive circuit's parameters,and the DC I-V curve was used to characterize the diode cells' nonlinear performance.The hybrid circuit model was established.On the basis of the hybrid model,a 2 mm band s... |
