There is a method in which impedance matching is performed by two matching transformers. In the above-mentioned two-way distributor, a required number of turns is wound around each core member forming one two-way distribution transformer and two matching transformers, and a distribution / matching set type is formed by connecting the terminals. Are known.
Here, in general, the two-way distributor has a distribution loss characteristic between an input terminal of the two-way distribution transformer and an output terminal of each matching transformer and a coupling loss characteristic between terminals between output terminals of each matching transformer. In the two divider, the smaller the distribution loss, that is, the smaller the absolute value of the characteristic value, the better.
Also, it can be said that the larger the coupling loss between terminals, that is, the larger the absolute value of the characteristic value, the better.

との位置関係によっても支配されることを見出した。In general, the distribution loss and the coupling loss between terminals of the above-mentioned two-way divider are generally higher in the higher frequency band of the high frequency band and lower in the lower frequency band as the number of windings of the winding is reduced. On the contrary, there is such a characteristic that the larger the number of windings of the winding, the better on the low side of the high frequency band and the worse on the high side. In addition to this characteristic, the distribution loss characteristic and the coupling loss characteristic between terminals (hereinafter referred to as transmission characteristic) of the two-way divider tend to rapidly deteriorate at different frequencies in the high frequency band. For this reason, it has been difficult to obtain a two-way divider having excellent transmission characteristics over a wide band for high-frequency signals. As a result of extensive studies, the inventors have found that in order to improve the transmission characteristics of the two-way splitter in a desired high-frequency band, in addition to changing the above-described factors to achieve the best condition, the inventors have also considered one more. It has been found that it is also governed by the positional relationship between the two-distribution transformer and the two matching transformers.
