摘　　要：为了减小太赫兹器件中频端口石英微带-同轴转换的插入损耗,提高信号传输效率,优化设计了金丝键合和绝缘子包金带两种微带-同轴互联方式。结合热超声键合工艺,对两种互联方式进行探讨。通过实物加工测试,得到两种互联方式的插入损耗,其中绝缘子包金带在0~33 GHz带宽内插入损耗小于0.33 dB,金丝键合在0~20 GHz带宽内插入损耗小于0.7 dB。可知绝缘子包金带互联方式能更加有效提高中频信号传输效率,可应用在混频器和倍频器等太赫兹器件的设计中。In order to reduce the insertion loss of quartz microstrip-coaxial conversion at the intermediate frequency port of terahertz devices and improve the signal transmission efficiency,two interconnection methods,gold wire bonding and insulator gold-coated strip,were optimized.Combined with thermosonic bonding technology,the two interconnection methods were discussed.The insertion loss of two interconnection methods was obtained by physical processing test.The insertion loss of insulator gold-coated strip is less than 0.33 dB in the bandwidth of 0~33 GHz,and the insertion loss of gold wire bonding is less than 0.7 dB in the bandwidth of 0~20 GHz.It can be concluded that the insulator gold-coated strip method can definite improve the transmission efficiency of IF signal,and can be used in the design of terahertz devices such as mixers and multipliers.
