摘　　要：宽带混频器由于其工作带宽大,变频损耗低,在通信、雷达以及微波毫米波测试仪器等系统得到广泛的应用。介绍了一种V波段鳍线单平衡混频器的设计过程并给出了测试结果。从单平衡混频器的基本原理出发,阐述了鳍线单平衡混频电路和矩形波导到鳍线的过渡结构的设计。最后制作出的宽带混频器在射频频率为50～75GHz的整个V波段内,变频损耗小于10dBm,并有良好的变频损耗平坦度。Because of broad-band mixer＇s broad working band and low conversion loss,it is often used in communication,radar and microwave measurement systems.In this paper,the design and the performance of a V-band single balance mixer based on fin-line circuit are described.From the theory of the single balance mixer,the design of the single balance mixer-circuit and the structure of waveguide to fin line are expounded.Finally,the conversion loss of this mixer is less than 10 dBm and has a good flatness when the mixer＇s RF is sweeping from 50~75 GHz.
