Patent ID: 8182103

Claim:
A millimeter wave power source module, comprising N submodules, where N is an integer greater than 1, each submodule comprising M circuit devices, where M is an integer greater than 1, each circuit device having an input and an output M radiating elements disposed in a linear array along a first side of each submodule, each radiating element coupled to the output of a corresponding one of the M circuit devices K receiving elements, where K is an integer less than M, disposed along a second side of each submodule, the second side opposed to the first side a K:M power divider having K input ports and M output ports, each input port coupled to a corresponding receiving element, and each output port coupled to the input of a corresponding one of the M circuit devices a heat spreader for removing heat from the M circuit devices a combination RF feed network and heat sink disposed adjacent to the second sides of the N submodules and thermally coupled to the heat spreaders of the N submodules along at least a portion of the second side of each submodule, the combination RF feed network and heat sink comprising a wavefront expander to receive an RF input wavefront, to expand the RF input wavefront along at least one axis, and to direct the expanded wavefront to the receiving elements on each of the N submodules.
