    摘要:

    主要介绍了0.68THz和1.00 THz频段平衡式三倍频。该三倍频是基于反向平衡式二极管和石英基片完成,而非集成电路。该工作主要的贡献在于提高了二极管等效电路模型,该二极管模型不仅仅包括I/V和C/V,同时还加入了等离子体共振和趋肤效应,将薄膜电路减薄至15um,机械加工精度提高至3um内,可使工作频率提高至1.2THz。通过场路协同仿真,利用高精度太赫兹装配工艺,最终实现工作频率为0.68THz和倍频效率为1%的三倍频器,工作频率为1.00 THz和倍频效率为0.6%的三倍频器,输出相对带宽均大于10%。

    Abstract:

    this paper introduces two designs of balanced frequency triplers in 0.68 THz and 1.00 THz bands. The proposed triplers are based on discrete antiparallel Schottky diodes and quartz glass instead of terahertz integrated circuit. The merits of this work are attributed to the improvement of the diode model, the thinned quartz glass film and the machining accuracy of the waveguide. The improved LEC diode model considers not only the current voltage (I/V) and capacitance voltage (C/V), but also plasma resonance and skin effect. The quartz glass film is thinned to 15um and can be used for up to 1.2 THz. The machining accuracy of the waveguide is ±3um for terahertz applications with channel size 60um. The measurement shows a peak output power above 160 μW and 60 μW for the 0.68 THz and 1.00 THz triplers, respectively. Moreover, the efficiency of the 0.68 THz and 1.00 THz triplers is around 1% and 0.6% correspondingly, and the 1.00 THz tripler is around. The output frequency bandwidth is both more than 10%.
