摘　　要：利用阻性二极管实现了一种D频段二倍频器,设计了一种新型双鳍线输入过渡结构,并成功应用于该二倍频器,该结构能更好地实现输入波导与二极管的匹配。该二倍频器采用肖特基势垒二极管MA4E2038,电路制作在0.05 mm厚石英基片上。仿真结果表明,在146.8 GHz处获得最高倍频效率10.3%。实物测试结果显示,在自偏置情况下倍频器在148 GHz处获得最高倍频效率2.3%,在0.7 V偏置电压下倍频器在154 GHz处获得最大输出功率1.1 mW。输出功率可以满足多数应用下对信号源的需求,该倍频器对处于大气窗口的140GHz通信系统具有借鉴作用。A D-band frequency doubler with resistive diodes is presented. A novel double finline input transition is designed to get better match of input waveguide with diodes, which has been successfully applied to this doubler. Commercial GaAs Schottky diodes MA4E2038 are employed. The doubler circuit is fabricated on 0.05mm thick quartz. Simulated results show that the highest conversions efficiency of 10.3% is obtained at 146.8 GHz. Practical highest conversion efficiency of 2.3% is measured at 148GHz when circuit is self-biased and maximum measured output power of 1. lmW at 154GHz when biased at 0.7V. The output power is high enough for most application, and the novel doubler could provide reference for communication system at 140GHz.
