Patent ID: 8686597

Claim:
A device configured to inject a plurality of signals onto a medium made up of (i) N conductors and (ii) a reference plane, the device comprising: E signal inputs, wherein E is between 1 and N, and wherein each of the E signal inputs is configured to respectively receive one of the plurality of signals to be injected onto the N conductors of the medium; E signal transformers configured to receive the plurality of signals from the E signal inputs, wherein the E signal transformers are configured to inject the plurality of signals by means of orthogonal modes between different conductors of the N conductors; and C differential mode chokes, wherein C is between 1 and E depending on a number of non-differential modes used, wherein, for each differential mode choke of the C differential mode chokes, the differential mode choke includes one input and two outputs, the input is connected to either (i) one end of a secondary winding of one of the E signal transformers, or (ii) one of the outputs of another one of the C differential mode chokes, and the two outputs are connected to either (i) the inputs of two others of the C differential mode chokes, (ii) the input of another one of the C differential mode chokes and a conditioner of one of the conductors, or (iii) conditioners of two of the conductors, wherein the injections that use the C differential mode chokes are injections selected from between (i) pseudo-differential injections, (ii) injection in common mode, or (iii) a combination of pseudo-differential injections and injection in common mode.
