Patent ID: 8248320

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 receiving elements, each coupled to the input of a corresponding one of the M circuit devices, M radiating elements, each coupled to the output of a corresponding one of the M circuit devices, and a heat spreader for removing heat from the M circuit devices; and a combination RF feed network and heat sink comprising: a wavefront expander to receive an RF input wave, to expand the RF input wave and to couple the expanded RF input wave to the M receiving elements on each of the N submodules, the wavefront expander including a horn to expand the RF input wave along at least one axis, wherein extended portions of the horn are thermally coupled to the heat spreaders of each of the N submodules.
