Abstract
A method of manufacturing a microstrip termination is provided, the microstrip termination containing a transmission line, a tapered edge ground and a thin film resistor connecting a transmission line to the tapered edge ground. Circuits are manufactured by first cutting holes in a substrate forming alignment holes for dicing the substrate into separate circuits. A saw is then used to cut tapered grooves along the alignment holes for forming tapered edges. The substrate is then plated and etched to form the transmission lines, thin film resistors, and ground planes. Finally, the substrate is diced into the separate termination circuits.
