Abstract:
A method for manufacturing circuits having microstrip termination, comprising the steps of:cutting a tapered edge into a substrate having a top surface and a bottom surface; depositing conductive material on the top surface, bottom surface, and tapered edge of the substrate; etching the deposited conductive material in order to form a transmission line on the top surface of the substrate and a tapered around plane on the tapered edge, the tapered around plane connecting the transmission line to the conductive material deposited to form a ground plane of the bottom surface of the substrate; etching the transmission line away in an area to form an area of thin film resistive material on the top surface of the substrate, the area of thin film resistive material adapted to terminate a signal propagating along the transmission line; and dicing the substrate in order to form individual circuits, each circuit having a transmission line an area of resistive material, and a tapered edge.
