ABSTRACT OF THE DISCLOSURE In a broadband signal switching matrix network having a cross-point matrix in FET technology whose switching elements, each controlled by a holding memory cell, are each formed with a series circuit of a switching transistor and of an input transistor, this series circuit (for a switching element situated in the through-connect state) forms a cross-point-associated, one branch of a differential amplifier whose other branch shared by the cross points connecting to one and the same matrix output line is formed by an identical or similar transistor series circuit of an output amplifier circuit that is individually associated to the matrix output line. Thus, the matrix output line is connected to one terminal of an operating voltage source via a source transistor.
