摘　　要：为了减小LTCC微带传输线损耗,提升电路传输性能,设计了一个LTCC50Ω标准匹配微带线实验。利用矢量网络分析仪测量了微带线损耗,并依据电子显微镜对电路的检测结果分析了损耗产生的原因。结果显示,在10GHz频率下,微带线损耗约为0.6dB。提出了减小微带线高频损耗的有效方法,如提高光绘膜精度和丝网精度等。To reduce the loss of micro-strip transmission lines and to improve the transmission performance of circuit,an experiment for the LTCC standard micro-strip transmission lines with a resistance of 50Ω was designed.The loss of micro-strip transmission lines was measured by the network analyzer,and the reasons for loss were provided through observing the circuit with SEM.The results show that the loss of micro-strip transmission line at 10 GHz is about 0.6 dB.Some effective measures to reduce the loss of micro-strip lines at high frequency are given.
