The present invention relates to a method of manufacturing a printed wiring board (PWB) of the type depicted in FIG. 1, and to the resulting PWB. Such a PWB comprises a first substrate and alternating layers of a second substrate and a metal layer. The layer 2 metallization of the PWB is a thick layer of a composite engineered metal material having a configurable coefficient of thermal expansion (CTE) to provide CTE matching with respect to radio frequency (RF) components mounted on the PWB, and having substantial heat dissipation properties to dissipate heat generated by the RF components. This composite metal layer also provides a ground plane for the RF components.
