ABSTRACT:
A transmission line for high-frequency differential signals and having a transforming impedance is formed into a substrate. The transmission line is comprised of a slot, the opposing surfaces of which carry a conductive surface capable of carrying electrical signals. The conductive surface on the opposing surfaces is gradually receded along a length of the slot. An The transmission line of claim 1, further including a non-air dielectric filling the space between the opposing faces in said second length of said slot, said non-air dielectric having a thickness that extends from the depth D, to the bottom of the slot at the first end of said second length, the thickness of the non-air dielectric continuously increasing along said second length up to the substrate surface at the second end of the second length. equivalent amount of metallization is applied on the substrate's surface and electrically continuous with conductive surfaces on the slot's opposing sidewalls. The metallization on the substrate's surface provide solder lands. Dielectric in the slot prevents solder wicking.
