ABSTRACT:
A device for detecting the power of incident or reflected waves along a transmission line is described which includes a capacitive pick-up element in series with a summing capacitor between the two conductors of the transmission line. The capacitive pick-up element provides a current sample through the summing capacitor in proportion to the line voltage. A coupling loop positioned in the approximate region of the capacitive pick-up element and in series resonance with the summing capacitor provides a current sample through the summing capacitor in proportion to the line current. The coupling loop is of highly resistive material to maintain the magnitude and phase of the developed line current sample relatively independent of frequency over a relatively broad range of frequencies.
