Abstract: In one embodiment, an electronic system includes a printed circuit board, one or more packaged semiconductor devices, and a vapor chamber having a top and a bottom and enclosing a sealed cavity that is partially filled with a coolant. The vapor chamber comprises a thermo-conductive and electro-conductive material. The top of the vapor chamber has one or more depressions formed therein, each depression receiving and thermo-conductively connected to at least part of a bottom of a corresponding packaged semiconductor device, which is mounted through a corresponding aperture in the PCB. A heat sink may be thermo-conductively attached to the bottom of the vapor chamber.

Abstract: Active antennas are provided that include a reflector defining part of an external heat dissipation surface and a plurality of radome elements coupled to the reflector (s). The reflector can include or be coupled to longitudinally extending walls that define heat dissipation surfaces and/or that provide RF isolation between neighboring columns of dipole antenna elements.
