description Direct radiating array ("DRA") antenna assemblies, methods of assembling a DRA antenna assembly, and systems for managing heat generated by a DRA antenna assembly are provided. A DRA antenna assembly includes: multiple radiating element modules, each radiating element module including a first dissipative component; multiple digital beamforming boards, each digital beamforming board having a radio frequency ("RF") connection to and servicing a subset of the radiating element modules and including a second dissipative component; and a thermal plate having a top surface and a bottom surface, the radiating elements and the digital boards mounted to the top surface and the bottom surface, respectively, such that the first and second dissipative components are heat sunk to the thermal plate. The thermal plate includes a plurality of passive two-phase flow devices embedded therein for transporting heat received from the first and second dissipative components away from an interior of the DRA assembly.
