One embodiment comprises a directional coupler system comprising a substrate having a top surface and a backside surface, with the backside surface comprising a metalization ground portion and an unmetalized portion. A power line is coupled to the top surface, with the power line having an input adapted to receive a power signal, a first trace coupled to the input, a second trace in parallel with the first trace and coupled to the input, and an output coupled to the first and second traces and adapted to emit the power signal. A sensor line is coupled to the backside surface unmetalized portion, with the sensor line adapted to emit a sensor line signal having a sensor line signal level generally proportional to the power signal. Finally, a thermo-conductive base platform coupled to the metalized portion of the backside surface. |
