0.14THz倍频器的设计与仿真
资料介绍
固态倍频器是毫米波及亚毫米波频段超外差接收机中的关键器件,其研制对太赫兹通信具有重要意义。介绍了一种基于肖特基变容二极管的宽带、高效率0.14 THz二倍频器的拓扑结构和仿真设计。该倍频器基于波导腔体石英基片微带电路形式,通过引线互联分别实现肖特基二极管接地和施加外部直流偏置,倍频器各部分采用了宽带电磁耦合结构设计。在开展了二极管建模及阻抗特性分析的基础上,采用三维有限元与非线性谐波平衡联合仿真方法,实现了倍频器的最优化设计。仿真结果表明,当输入频率为65 GHz~75 GHz,驱动功率为20 dBm时,倍频器的输出功率最高达10.1 dBm,倍频效率达10.8%。
