Title: Telecommunications signal amplifier

Abstract: A telecommunications signal amplifier comprising an active tripole the transfer function of which has a negative real portion, the input impedance and the output impedance of which are substantially equal to one another and to the iterative impedance of the line in which the amplifier according to the invention is inserted, a first dipole of defined structure, a second dipole of structure reciprocal to the first with respect to the iterative impedance of the circuit in which the amplifier according to the invention is inserted, characterised in that said signal amplifier is reduced to a tripole by merging an input terminal and an output terminal, the other input terminal is connected to a terminal of said first dipole and to an input terminal of said tripole, the other output terminal is connected to the other terminal of said first dipole and to an output terminal of said tripole, the common input and output terminal of this tripole being joined, by means of said second dipole, to the common input and output terminal of the telecommunications signal amplifier.
