Abstract
In a package for integrated circuits, a signal transmission line has a first segment closer to the chip that is bracketed vertically by ground planes at a first vertical distance and a second segment further from the chip that is bracketed vertically by ground planes at a second vertical distance greater than the first distance, with an aperture being formed in the ground planes at the first distance, so that those ground planes do not interfere with the impedance set by the second set of ground planes.
