Abstract:
1. A crossbar switch, comprising: a number of rows and a number of columns crossing the rows at crossing points; a row input at each row configured to receive an input signal supplied to each row; controllable switch elements arranged at the crossing points via which an input signal supplied to a row is switched to a column crossing this row at this crossing point when a switching signal is supplied to the respective crossing point; a column output to which a switched input signal is delivered as an output signal at each column; amplifier elements of the controllable switch elements that comprise an amplifier input and an amplifier output, wherein the amplifier inputs are connected with the rows and the amplifier outputs are connected with the columns and are arranged equidistant along the rows, the amplifier elements comprising input capacitances and are wired such that they only consume electrical energy when the switching signal is supplied to the respective crossing point; and row wave resistors that are arranged at ends of the rows opposite the row inputs, a row voltage being applied to the rows via the row wave resistors; wherein: row conductors are fashioned such that they likewise have the resistance value of the row wave resistor, taking into account the input capacitances.
