A stacked electronic arrangement provides independent upgradability of active component boards and radiator boards, enabling quick changes in chip set and alternate polarizations, and includes: an active tile circuit card assembly (CCA); a passive radiator CCA; a tile frame; and a heat exchanger. The active tile CCA includes transmit/receive modules that accept, amply and transmit radar signals. The passive radiator CCA includes patch radiator plugins that receive and then radiate the amplified signal from the modules. The tile frame separates the active tile and the passive radiator CCAs. An elongated casing of the heat exchanger creates an accommodating space for air flow, and forms a first inlet, a second inlet, and a central exhaust plenum between the first and second inlets. High density fins are positioned within the accommodating space between the first and second inlets, and which have openings to the exhaust outlet.
