An improved multi-layered ceramic package includes a plurality of signal planes, each having one or more signal lines; a plurality of vias, each providing one of a voltage (Vdd) power connection or a ground (Gnd) connection; and at least one reference mesh plane adjacent to one or more signal planes. The reference mesh plane includes spaced mesh lines that are separated by spaces that alternate in a narrow-wide or wide-narrow pattern. A multi-layered ceramic package using the mesh plane with alternating spaces generates significantly lower far-end (FE) noise in the ceramic package than a conventional mesh plane with constant spaces. The noise is further reduced by placing shield lines on opposite sides of signal lines in the signal plane.
