Abstract
A balanced branching transmission branch device, in which two relatively decoupled branch branches are coupled by means of a transformer with a common branch branch, characterized by the fact that the transformer comprises two identical coupling windings, which are inductively coupled with a winding connected to the common branch of the branch, the ends of the last winding constituting the connecting terminals for the common branch of the branch, while corresponding ends of the two identical coupling windings are connected to each other through a resistor and the connecting terminals for the two decoupled branch branches are formed by one end of a coupling winding and by one end of the other coupling winding, ends that are not connected to each other by a branch resistor, the values of said resistors, substantially i equal to the characteristic terminal impedances of the decoupled branch branches.
