Abstract

PURPOSE:To obtain a branching device having a wide range of frequency with a low loss, by connecting an impedance converting transformer to the other end of a resistance having an end connected to an input terminal and then connecting a branching transformer to the point of connection of the impedance converting transformer. CONSTITUTION:A primary winding 21 of a branching transformer 20 is connected between an input terminal 1 and an output terminal 4, and an end of a secondary winding 22 is grounded. A resistance 25 is set between an end of a primary winding 24 of an impedance converting transformer 23 and the terminal 1, and the other end of the winding 24 is grounded. An end of the transformer 26 of the transformer 23 is connected to a branching terminal 6, and the other end of the winding 22 of the transformer 20 is connected to the joint 27 between the resistance 25 and the winding 24 of the transformer 23. The equivalent resistance value of the resistance 25 which is viewed from the terminal 6 is reduced by the transformer 23 to facilitate the matching of impedance.
