ABSTRACT:
An n.times.m wideband RF switching matrix constructed from modules which are interconnected by simple series paths. As many modules as required can be juxtaposed to form switching matrices of any order. Each module includes n inputs and a different lumped element directional coupler connected to each input, each directional coupler having a coupled output. Each module further includes a conductor coupled to a matrix output. The coupled outputs of the directional couplers on a given module are connected through single-pole, single-throw switches to the conductor. The direct outputs of the directional couplers are coupled to the inputs of the n directional couplers on the next module in the series.
