发明名称 BROADBAND SIGNAL SWITCHING EQUIPMENT
摘要 A crosspoint matrix has matrix input lines which lead via pairs of switching elements to matrix output lines having, respectively, two signal conductors which are respectively connectible to a reference potential source via a precharging transistor controlled by a precharging clock and which have signal inputs of a differential amplifier with a trigger behavior connectable thereto. The pair of switching elements respectively comprise two input transistors that have their control electrodes connected to a signal conductor of the appertaining matrix input line and form a series circuit with arespective switching transistor leading to the one or, respectively, other output signal conductor, a logic element that is respectively oppositely controlled by the precharging clock is inserted into the input lines and, in the switching elements, the ends of the series circuits facing away from the matrix output line are directly connected to the appertaining terminal of the operating voltage source.
