    摘要: A broadband matrix switching system switches a plurality of output loads to any of a plurality of input signal sources. Modular printed circuit cards which carry cross-point switches and transmission lines are mounted on a motherboard; an input distribution card being provided for each input to the matrix switching system and an output selection card being provided for each output. The input distribution cards have distribution networks and low capacitance cross-point switching cells which provide selective connections to all of the output select cards via transmission lines on the input transmission lines and other transmission lines carried by the motherboard. The input distribution card further provides a termination which is of value equal to the characteristic impedance of each input signal source. The switches on the input cards connect each output of the input distribution cards to either an output select card or a dummy load resistor which is of value equal to the characteristic impedance. Through the use of signal carrying lines of the same length and the cross-point switches located in accordance with a geometry which standardizes the path lengths to the cards, the effects of any mismatched impedances are minimized to thereby provide for improved frequency response characteristics, constant propagation delays, reduced voltage standing wave ratio, and improved cross-talk characteristics.

    摘要: A relay system or relay block consists of stacked reed relays each housed in an envelope. Said relays are supported by pairs of spaced parallel relay supports which, in turn, are received by a frame structure having a front panel including printed circuitry means for properly interconnecting the constituent reed relays of the relay system or block, and for connecting the relay system or block with external equipment.
