摘要
本文介绍一种基于平面肖特基势垒二极管的220GHz平衡式二倍频器设计。通过输入、输出信号的电磁场模式变化实现平衡结构,并控制偏置电压和输入功率使二极管工作于变容模式。采用HFSS和ADS联合仿真获得最佳二极管嵌入电路,输入功率为50m W时得到最佳变频效率为21%,在212GHz至235GHz范围内变频损耗优于8d B。
We present a design of balanced configuration doubler based on planar schottky diodes. The balanced configuration is accomplished through the variation of electromagnetic field mode of input and output signal, and make diodes work in varactor mode by controlling signal power and bias voltage. We get the optimum embedding circuits by the co-simulation of HFSS and ADS. The best conversion efficiency is 21% when signal power is 50 mw, the conversion loss is less than 8d B at the output frequency from 212 to 235 GHz band.
