Abstract:
A phased array antenna includes an antenna housing including a subarray assembly and a plurality of beam forming modules positioned on the subarea assembly. An antenna support and interconnect member are mounted on the antenna housing and include a carrier member having a front antenna mounting surface substantially orthogonal to the module support for supporting at least one antenna element. A rear surface has a receiving slot. At least one conductive via is associated with the receiving slot and positioned to extend through the carrier member to a circuit element, such as an antenna element, supported by the mounting surface. A launcher member is fitted into the receiving slot and has a module connecting end that extends rearward to a beam forming network.
Abstract:
A thermally enhanced microcircuit package includes a microcircuit having a microcircuit device cavity that receives a microcircuit device. A microelectromechanical (MEMS) cooling module is operatively connected to the microcircuit package and forms a capillary pumped loop cooling circuit having an evaporator, condenser and interconnecting cooling fluid channels for passing vapor and fluid between the evaporator and condenser and evaporating and condensing the cooling fluid.

Abstract:
A microelectromechanical structure having a ceramic substrate formed from low temperature co-fired ceramic sheets. A low loss photodefinable dielectric planarizing layer is formed over one surface of the ceramic substrate. This layer can be a sacrificial layer or a subsequent sacrificial layer added. A photodefined conductor is printed over the low loss dielectric planarizing layer and formed with the sacrificial layer into a structural circuit component. A switch is formed with a biasing actuator and deflectable member formed over the biasing actuator and moveable into open and closed circuit positions.
Abstract:
An electronic module (20) includes a cooling substrate (21a), an electronic device (22) mounted thereon, and a heat sink (23) adjacent the cooling substrate (21a). More particularly, the cooling substrate (21a) may have an evaporator chamber (25) adjacent the electronic device (22), at least one condenser chamber (26) adjacent the heat sink (23), and at least one cooling fluid passageway (27) connecting the evaporator chamber (25) in fluid communication with the at least one condenser chamber (26). Furthermore, an evaporator thermal transfer body (28) may be connected in thermal communication between the evaporator chamber (25) and the electronic device (22). Additionally, at least one condenser thermal transfer body (36) may be connected in thermal communication between the at least one condenser chamber (26) and the heat sink (23). The evaporator thermal transfer body (28) and the at least one condenser thermal transfer body (36) preferably each have a higher thermal conductivity than adjacent cooling substrate portions.
