摘　　要：在移动通信和其他一些电子设备上都对电路提出了宽带的要求，其中就常常要用到有效的阻抗匹配变压器，理论表明传输线变压器可以实现多种阻抗变换比，并且在很宽的频带上，从几十KHz到几千MHz都有良好的宽带阻抗匹配特性。传输线变压器体积可以被做得很小，通过使用铁氧体磁环可以得到很好的电路特性。Broad circuits, now widely used in mobile radios and other equipment, often require efficient impedance──matching transformers. Theory indicates that the transmission line transformer with many resistance radios has perfect broadwide impedance──matching property in the frequency range of a few tens of kilocycles to over several thousands megacycles. The transmission line transformers can be made quite small and excellent property have been made using ferrite torosids.
