Switchable transmission system having an input and two outputs for the avoidance of transmission of cases, in satellites - systems

摘要

The present invention relates to a switching device, a channel to two, comprising a portion of the input line and two portions of the output lines, defining two possible paths of propagation of the electromagnetic signals delivered by said portion of the input line at the point of intersection, each portion of the output line comprising an electronic component with two states on or off depending on the application of a control signal and located in one of the two abovementioned states in the absence of a control signal, these two electronic components which are identical, each being mounted in series or in parallèle.dispositif characterized in that it has an asymmetrical structure, the two paths of propagation (1 - 2 and 1 - 3) can be differentiated by their configurations and / or by the parity of their electrical lengths, expressed as a quarter wave lengths, between the said components (4, 4 ′) and the point of junction (a), so that, whatever the state of said components, one of the two channels is open and the other channel is blocked.
