ABSTRACT:
A collinear terminated transmission line structure and method for producing same is presented. The structure comprises a plurality of conductors electrically connected to a plurality of resistors. A predetermined spacing between each of the plurality of conductors ranges from 2 mils to 7 mils. Greater spacings are easily accomplished with the present method. The method comprises the steps of screen-printing a resistor swath onto a substrate, the swath being adjacent to one end of the plurality of conductors. After the substrate is dipped into a solution, the resistor swath is laser trimmed to form the plurality of resistors. The substrate is then rinsed with warm water to remove the solution. The solution can be a poly-vinyl alcohol and isopropyl alcohol mixture.
