ABSTRACT:
A coaxial impedance matching device employing film resistors in place of conventional rod and disc resistors. In a preferred embodiment, an elongated rectangular film resistor is deposited across the middle of a square insulation substrate with a pair of metal strips along opposite edges of the substrate and contacting the ends of the film resistor. Center metalized contacts are made to opposite sides of the film resistor, the lengths of contact with the sides being determined by the impedances of the cables to be connected thereto.
