ABSTRACT:
The device of the invention comprises a bus (B) constituted by a series of lengths each of constant width and each of arbitrary length. The widths of the different lengths vary along the bus from one length to another, with the length connected to an emitter (E) being the widest. Each junction between two lengths is connected by a branch line (L2 to Ln) to an electronic circuit (D2 to Dn). The lines are of arbitrary lengths and have the same characteristic impedance. The end length (B1) of the bus is connected to an electronic circuit (D1). The end length and the branch lines are all terminated on their characteristic impedance. When signals are distributed symmetrically, distribution takes place from a differential emitter via two identical buses which are connected via differential lines to the electronic circuits.
