摘　　要：介绍了一个基于石英基片的二毫米频段三倍频器.采用反向并联变容二极管对结构实现倍频.建立了该二极管管对的等效电路模型并提取了模型参数.设计实现的倍频器输入为K型接头结构,输出为WR-8波导结构.获得的倍频器在输出频率为112.8～118.2 GHz范围内,输出功率大于0 dBm,最大输出功率超过2 dBm,最小倍频损耗为16 dB,可为气象探测系统中毫米波前端提供本振源.A 2mm-band frequency tripler built on quartz was formed by anti-parallel Schottky-barrier varactor diode pair.Its equivalent circuit model had been built and the component parameters were obtained.Then the tripler was designed and realized.Its input signal was fed in by a K connector,and the output signal was fed out by a WR-8 waveguide.When the output signal frequency is between 112.8 GHz and 118.2 GHz,the best conversion loss is 16 dB and the output power is larger than 0 dBm with maximum 2.05 dBm at 118 GHz.The tripler module can supply good local oscillation source for the meteorological measurements.
