摘　　要：针对气象监测辐射计的应用,文章提出了基于肖特基平面二极管混合集成的W波段89 GHz二次谐波混频器。以毫米波混频技术基本理论为基础,根据对二极管的三维仿真精确建模赋予其材料特性,并结合场路联合仿真研制了结构精巧的W波段的89 GHz二次谐波混频器。仿真与测试结果表明,本振信号频率固定在45 GHz,射频信号频率在84~94 GHz时,变频损耗优于14 dB,最低为9 dB,其实测结果与仿真趋势相对吻合,有良好的工程应用前景,同时有效证明了建模方法的正确性。A hybrid integrated 89 GHz sub-harmonic mixer based on Schottky diode was proposed for meteorological monitoring radiometer.In this paper,based on the theory of millimeter wave mixing technology,a three-dimensional electromagnetic model of diode is established in the field simulation software,and a W-band 89 GHz sub-harmonic mixer is designed based on the three-dimensional electromagnetic model.The simulation and test results show that when the Local Oscillator(LO)is fixed at 45 GHz,the conversion loss is better than 14 dB from 84 to 94 GHz,and the minimum conversion loss is 9 dB.The measured results are consistent with the simulation results.
