    摘要:

    介绍了一种基于砷化镓材料的高功率490~530GHz单片集成三倍频器。基于提出的对称平衡的结构,该三倍频器不仅可以实现良好的振幅和相位平衡,用来实现高效的功率合成,还可以在没有任何旁路电容的情况下提供直流偏置路径以保证高效倍频效率。同时开展容差性仿真分析二极管关键电气参数与结构参数对倍频性能的影响,以便最大化提升倍频性能。最终,在大约80~200 mW的输入功率驱动下,研制的510GHz三倍频,在490~530GHz频率范围内,输出功率为4~16mW,其中峰值倍频效率11%。在522GHz频点处,该三倍频在218mW的输入功率驱动下,产生16mW的最大输出功率。该三倍频器后期将用于1THz的固态外超外差混频器的本振源。

    Abstract:

    A high power 490~530 GHz monolithic integrated frequency tripler is demonstrated based on Gallium Arsenide material. Based on the proposed symmetrical and balanced configuration, the tripler could not only achieve good amplitude and phase balances for efficient power synthesis, but also provide a DC bias path without any bypass capacitor to ensure efficient frequency doubling efficiency. Tolerance simulations are also carried out to analyze the effects of key electrical and structural parameters of the diode on the frequency doubling performance in order to maximize the frequency doubling performance. Finally, the developed 510GHz triplet, driven by approximately 80~200 mW input power, has an output power of 4~16 mW in the frequency range of 490~530GHz, where the peak frequency doubling efficiency is 11%. At the 522GHz frequency point, the triplex produces a maximum output power of 16mW driven by an input power of 218mW. The triplexer will later be used as the local oscillator source for a 1 THz solid-state external super outlier mixer.
