- 21 - ABSTRACT OF THE DISCLOSURE The invention relates to a quadrupole for resistive matching of a reactance of the RLC type connected in series or in parallel, which permits to compensate for the loss of gain of an amplifier as the frequency rises, in a manner independent of the frequency. This quadrupole comprises two impedance circuits Z1 and Z2 in series between an input terminal and an output terminal, and in parallel with these, a third impedance circuit Z3. It also comprises a fourth impedance circuit Z4 connected between the point common to the first two circuits Z1,Z2 and the point common to the two other terminals of the quadrupole. The reactance which is to be matched is Z3 if it is of the RLC type connected in parallel. It is Z4 if it is of the RLC type connected in series. The values of the three other impedances Z1,Z2 and Z4 or Z3 are related so that the input impedance may be equal to the output impedance.
