  • Patent number: 8248320
    Abstract: A millimeter wave power source module may include N submodules, each of which includes M circuit devices, where M and N are greater than one. Each circuit device may have an output connected to a corresponding radiating element. Each submodule may include a power divider having K input ports and M output ports, where K is a factor of M. Each input port may be coupled to a corresponding receiving element, and each output port may be coupled to an input of a corresponding circuit device. Each submodule may include a heat spreader for removing heat from the circuit devices. The power source module may include a combination RF feed network and heat sink. The combination RF feed network and heat sink may include a wavefront expander to expand the RF input wavefront along at least one axis, and to direct the expanded wavefront to the receiving elements of the N submodules. The combination RF feed network and heat sink may also include a heat exchanger thermally coupled to the heat spreaders of the N submodules.

  • Patent number: 7902979
    Abstract: There is disclosed apparatus and methods for a directed energy beam virtual fence. The directed energy beam virtual fence may include a source unit to provide an energy beam and a sequence of relay units disposed at intervals along the length of the virtual fence. Each relay unit in the sequence may receive the energy beam from a previous unit and may recollimate and redirect the energy beam towards a subsequent unit.

  • Patent number: 7715091
    Abstract: A spatially-fed high-power amplifier comprises one or more shaped reflectors to reflect an initial wavefront, and an active array amplifier to amplify the reflected wavefront to generate a high-power planar wavefront. The shaped reflectors provide the reflected wavefront with substantially uniform amplitude when incident on the active array amplifier. The initial wavefront may be a substantially spherical wavefront, and the shaped reflectors may compensate for any amplitude taper of the initial wavefront to provide the reflected wavefront with substantially uniform amplitude components for incident on the active array amplifier. In some embodiments, the shaped reflectors may also contour the illumination to fit the shape of the active array amplifier to help minimize spillover.
