摘　　要：在四倍频器设计中首先对二极管进行I-V曲线、C-V曲线、等离子振荡和趋肤效应等进行计算,完成肖特基二极管电路建模;通过谐波和三维电磁仿真工具优化电路中各次谐波最佳阻抗值;通过引入改进紧凑型悬置微带线震荡器(Compact Suspended Microstrip Resonators(CSMRs))滤波器,成功将二次和三次谐波短路,同时减小长宽比,满足装配条件。实验表明,四倍频在334~346 GHz频段内输出功率均大于1 mW,最大输出4 mW,当驱动功率为100 mW时,最高效率可达3%。High frequency and power source is most important for terahtz technology, and multipliers is common electronic way. This quadrupler design is only one stage to avoid impedance mismatches be- tween multipliers. A proposed Schottky diode model improves the accuracy of design, which has con- sidered the behaviors of current voltage （ l/V）, capacitance voltage （ C/V）, plasma resonance, and skin effect. Theoretical analysis was carried out by using harmonic balance simulations programs and three-dimensional finite element simulation tools to find the optimum embedding impedance for a given diode. Compact Suspended Microstrip Resonators （CSMRs） minimize the length/width ratio and make short idlers at the 2nd and 3rd harmonics. The experiment shows： the quadupler works at 325 -351 GHz and output power is above lmW between 334 GHz and 346 GHz, and the highest efficiency is above 3% with input power of 100 mW.
