0.67 THz sub-harmonic mixer based on Schottky diode and hammer-head filter
摘要
通过测量肖特基二极管的I-V和C-V曲线,建立等效电路模型.利用三维电磁场和谐波平衡仿真工具分别进行三维结构仿真和电路宽带匹配,最终实现混合集成方式的0.67THz谐波混频器设计.测试结果表明：混频器中心频率为0.685 THz,射频3 dB带宽为47 GHz,双边带变频损耗13.1~16 dB,在685 GHz双边带噪声温度最低值为11500 K.
Abstract
Equivalent circuit for the Schottky diode was established based on measurement results of I-V and C-V curves. The design of 0.67THz sub-harmonic mixer included three-dimensional structures and broadband matching circuits. Results show that the 3dB bandwidth of RF is 47GHz with the center frequency at 0.685THz. The double-sideband conversion loss is between 13.1dB and 16dB. The lowest double-sideband noise temperature is 11500K at 685GHz.
