Abstract
A radio frequency (RF) module having a plurality of channels includes a heat sink having at least one tapered edge; a substrate disposed over a surface of the heat sink such that the tapered edge of the heat sink extends past a boundary of the substrate. RF, logic and power circuitry is disposed on the substrate and one or more RF signal ports are formed on an edge of the substrate to allow the RF module to be used in an array antenna having a brick architecture. The tapered edge heat sink provides both a ground plane for RF signal components and a thermal path for heat generating circuits disposed in the substrate.
