摘　　要：本文介绍不平衡—平衡转换器指数线的长度计算和指数线输入端补偿电感的计算,并详细阐述了在发射机输出窗口到馈线入口端之间安装不平衡—平衡转换器,该不平衡—平衡转换器采用电感补偿环路型(Balun)以实现50Ω—300Ω的阻抗转换和阻抗匹配。This article describes the calculation of the length of the exponential transmission line and the calculation of the t inductor compensation in input of the exponential transmission line, and described in detail unbalanced to balanced converter is installed between the output of the transmitter to the input of the feeder, it is by the inductive loop- based compensation （Balun） to achieve impedance conversion and impedance matching from 50 Ω to 300Ω.
