Filed:

Dec 12, 2000

Appl. No.:

09/734868

Inventors:

Richard Earl Miller - Mt. Laurel NJ
Robert Michael Reese - Philadelphia PA

Assignee:

Lockheed Martin Corporation - Moorestown NJ

International Classification:

H01Q 322

US Classification:

342368, 342174

Abstract:

An array of antenna elements is arranged to calibration by assigning certain ones of the elements to be âkernelâ elements. The kernel elements are coupled to the beamformer by way of a directional coupler arrangement, and calibration ports are coupled to ports of the directional coupler. Calibration includes applying signal to a first calibration port of a kernel element and determining the amplitude andor phase of the calibration signal paths. Signals are applied to the beamformer ports feeding the kernel element, and the lengths of the beamformer-plus-calibration paths are determined. From these, the beamformer paths to the kernel elements are determined. Other non-kernel antenna elements near the kernel elements are calibrated by applying signal through the beamformer to the non-kernel element, and receiving the signal through a calibration path of the kernel element.

International Classification:

H01L 2334

US Classification:

257713, 257714, 257721

Abstract:

A cooling arrangement useful for semiconductors or solid-state assemblages mounts the semiconductor or other solid-state device directly onto a first surface of a thermally conductive âheat spreader. â The heat spreader contains microchannels which open into coolant fluid ports on the second side of the heat spreader. The heat spreader, in turn, is mounted on a coolant fluid distribution or circulation plate. In one embodiment, the coolant fluid distribution plate also includes a micropump for circulating coolant fluid through the microchannels of the heat spreader. In another embodiment, the coolant fluid distribution plate simply distributes coolant applied to its fluid input port to those heat spreaders mounted thereon, and a plurality of coolant fluid distribution plates are mounted on a coolant fluid circulation plate, which uses a micropump to circulate coolant fluid to the various distribution plates and ultimately to the heat spreaders. Thus, coolant fluid is communicated directly into the support for the semiconductor chip or other solid-state device, for good heat transfer with low temperature drop. ( ).

Appl. No.:

09/905834

Inventors:

Brian Alan Pluymers - Haddonfield NJ
Robert Michael Reese - Philadelphia PA

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

H01Q 124

US Classification:

343702, 343700 MS

Abstract:

A generally planar active array antenna includes a plurality of transmit-receive (TR) modules arrayed in an array direction on a generally planar heat-conducting baseplate of a line-replaceable unit (LRU). Heat is coupled from the TR modules to their associated baseplate. Each baseplate of an LRU has a straight edge parallel to the array direction of the modules. In a preferred embodiment, the modules are located adjacent the straight edge without significant intermediary components. The LRUs are arrayed with their straight edges lying in a plane. The straight edges are coupled to a generally planar cold plate for extracting heat from the baseplates. Since the heat is extracted in a direction orthogonal to the arraying direction of the modules, all the modules tend to have the same operating temperature. In a particularly advantageous embodiment, the circulators associated with each TR module are mounted on the opposite side of the cold plate relative to the module, to thereby minimize the thermal path length between each module and the cold plate.

Inventors:

Robert M. Reese - Philadelphia PA

Assignee:

General Electric Company - Moorestown NJ

International Classification:

H01P 118

US Classification:

323212

Abstract:

A compact, liquid cooled, ferrite phase shifter is capable of handling high power microwave signals without thermally stressing the ferrite core. The ferrite core is mounted on spacers inside of a hermetically sealed wave guide filled with a thermally conducting fluid. Heat transfer from the core to the housing is symmetrical thereby eliminating or minimizing thermal bending stresses on the phase shifter. Heat from the core is also coupled through the fluid to the phase shifter window for deicing the window.

International Classification:

H01Q 1/02
H01Q 1/42

Abstract:

A radome membrane bladder and systems and methods thereof can comprise an inner membrane having an inner surface and an outer surface opposite the inner surface, an outer membrane having an inner surface facing the inner membrane and an outer surface facing away from the inner membrane, and at least one port configured to control the supply of air provided between the inner membrane and the outer membrane. At least the outer membrane is movable between a state where no air is provided between the inner membrane and the outer membrane and an outward state when air is being provided or has been provided between the inner membrane and the outer membrane. Movement of the outer membrane can prevent, minimize, and/or remove ice or snow or other foreign material buildup on the outer surface of the radome (i.e., the outer surface of the outer membrane).
