摘要
基于反向串联型砷化镓平面肖特基容性二极管,采用平衡式二倍频结构,研制出了一种190GHz大功率输出二倍频器。使用三维电磁场与非线性谐波平衡联合的方法进行了仿真,并根据仿真结果完成了倍频器的加工、装配和测试。倍频器在182~196GHz输出频率范围内的倍频效率可达8%以上;当输出频率为187GHz时,倍频效率和输出功率可分别达到15.4%和85mW。
Herein,a 190-GHz frequency doubler with a high output power is designed and realized using a balanced double-frequency construction based on the anti-series gallium arsenide planar Schottky varactors.A method that combines a three-dimensional electromagnetic field and nonlinear harmonic balance is employed to conduct a simulation.The simulation results demonstrate that the proposed frequency doubler has been effectively fabricated, assembled,and tested.The frequency-doubling efficiency of the proposed doubler can reach more than 8%in the output frequency range of 182-196GHz.Moreover,at an output frequency of 187GHz,the frequency-doubling efficiency and the output power can reach 15.4%and 85mW,respectively.
