本专利介绍宽带传输性能良好,又能匹配阻抗的不平衡—平衡变换变压器。不平衡—平衡变换变压器有如图1至图4所示的各种形式。图1所示的形式是把初级线圈1,2和次级线圈3,4以及5,6适当地绕在铁芯7上,但是这种不平衡一平衡变换变压器绕线困难,并且很难获得良好的不平衡电压衰减特性和宽带不平衡一平衡变换特性。图2的变压器是将线圈绕在铁芯16,17上的、用于超短波和电视的传输线变压器,缺点是难以得到良好的不平衡电压衰减特性。图3的变压器是将线圈的一半21—22用同轴线,把它的芯线(中心导体)接到另一半线圈24—25上。这种变压器基本上可获得较好的不平衡一平衡变 This patent describes the broadband transmission performance is good, but also to match the impedance of the unbalanced - balanced transformers. Imbalance - Balance Transformer There are various forms shown in Figure 1 to Figure 4. The form shown in Fig. 1 is such that the primary coils 1, 2 and the secondary coils 3, 4 and 5, 6 are appropriately wound on the iron core 7, but this unbalanced-a.c. transformer transformer is difficult to wire and hard to obtain Good unbalanced voltage attenuation characteristics and broadband imbalance-a-shift characteristics. The transformer of Fig. 2 is a transmission line transformer for winding an iron core 16, 17 for ultrashort wave and television with the disadvantage that it is difficult to obtain a good unbalanced voltage attenuation characteristic. The transformer of FIG. 3 uses the coaxial half of the coil 21-22, and its core (center conductor) to the other half of the coil 24-25. This transformer can basically get a better balance of a balanced change
