    • A generally planar active array antenna includes a plurality of transmit-receive (TR) modules arrayed in an array direction on a generally planar heat-conducting baseplate of a line-replaceable unit (LRU). Heat is coupled from the TR modules to their associated baseplate. Each baseplate of an LRU has a straight edge parallel to the array direction of the modules. In a preferred embodiment, the modules are located adjacent the straight edge without significant intermediary components. The LRUs are arrayed with their straight edges lying in a plane. The straight edges are coupled to a generally planar cold plate for extracting heat from the baseplates. Since the heat is extracted in a direction orthogonal to the arraying direction of the modules, all the modules tend to have the same operating temperature. In a particularly advantageous embodiment, the circulators associated with each TR module are mounted on the opposite side of the cold plate relative to the module, to thereby minimize the thermal path length between each module and the cold plate.
    • 大体上平面的有源阵列天线包括在线路可替换单元(LRU)的大致平面的导热基板上的阵列方向上排列的多个发射 - 接收(TR)模块。 热量从TR模块耦合到其相关的底板。 LRU的每个基板具有与模块的阵列方向平行的直边。 在优选实施例中,模块位于直边边缘附近,而没有显着的中间部件。 LRU排列成直边位于平面内。 直边缘连接到大体平面的冷板,用于从基板提取热量。 由于在与模块的排列方向正交的方向上提取热量,因此所有模块倾向于具有相同的工作温度。 在特别有利的实施例中,与每个TR模块相关联的循环器相对于模块安装在冷板的相对侧上,从而使每个模块与冷板之间的热路径长度最小化。
