According to an embodiment of the present invention, a subassembly for a phased array radar includes a substrate generally lying in a first plane, the substrate including a plurality of transmit/receive modules coupled to a mounting surface and a plurality of radiating elements formed adjacent the mounting surface, and a multi-function board generally lying in a second plane parallel to the first plane. The multi-function board is in spaced apart relation to the substrate and may include RF manifolding and logic/power distribution functions for the transmit/receive modules.

Subassembly for an active electronically scanned array

According to an embodiment of the present invention, a multi-function carrier structure for a phased array radar includes a substrate that includes a mounting surface for a plurality of transmit/receive modules, a plurality of radiating elements integrally formed in the substrate adjacent the mounting surface, and a plurality of cooling channels integrally formed within a thickness of the substrate. The substrate is formed from a material having a coefficient of thermal expansion similar to respective substrates of the transmit/receive modules.

Integrated subarray structure

According to an embodiment of the present invention, a transmit/receive module for a phased array radar includes a substrate, a ground plane formed outwardly from the substrate, and one or more dielectric layers formed outwardly from the ground plane. The one or more dielectric layers have RF and DC routing formed therein. The transmit/receive module further includes an electronic device coupled outwardly from the one or more dielectric layers, and a lid coupled to a portion of the one or more dielectric layers.

Transmit/receive module and method of forming same

An apparatus includes a plurality of Transmit/Receive (T/R) modules () coupled with a slat assembly (). The slat assembly includes a fluid passageway (). A plurality of turbulence inducing structures () are disposed within the fluid passageway. In one embodiment, the turbulence inducing structures includes constrictions () extending from a surface () of the fluid passageway. The location and configuration of the structures is selected to achieve a predetermined temperature profile along the passageway, in response to fluid flow through the fluid passageway.

Method and apparatus for temperature gradient control in an electronic system

A system for cooling, positioning and supporting phased array microwave modules within a phased array radar system wherein the modules are disposed in cooling tubes, the cooling tubes being arranged to permit coolant to continuously pass in close proximity thereto along channels formed in a coldplate. The channels can be built into a solid member wherein the cooling tubes are hollowed out portions of the solid with channels for coolant formed in the space between cooling tubes. In alternate embodiments, the channels are formed by the spaces between cooling tubes.
