Aspects of the present invention are related to systems and methods for rendering graphical objects in a printing system. The distributed radio frequency amplifier 110 drives an output load, such as an antenna 114. The hybrid matrix fiber composites include two chemically or physically bonded matrix materials, whereas the first matrix materials are used to impregnate multi-filament fibers formed into ribbons and the second matrix material is placed around and between the fiber ribbons that are impregnated with the first matrix material and both matrix materials are cured and solidified. A first sidewall extension is integrally connected to and extends orthogonally with respect to the first sidewall, and includes a first planar mount surface. Another shim layer is placed on each side of the central substrate layer.
