Applied Radar has developed a multi-channel wideband digital receiver/exciter (DREX) module denoted as the Single Channel Open Architecture Receiver Exciter (SCORE-X750) which operates at X-band (tunable over 812 GHz) with 750 MHz of instantaneous bandwidth. This DREX module is designed for ground-based radars and can be used in new designs or in retrofit and modernization of existing radars. The ...

HIGH QUALITY WAFER OF MERCURY CADMIUM TELLURIDE ARE CRITICALLY NEEDED FOR THE FABRICATION OF INFRARED FOCAL PLANE ARRAYS. DEFENSE RELATED APPLICATIONS OF THESE ARRAYS INCLUDE: SURVEILLANCE, TARGET DETECTION, ACQUISITION AND TRACKING, MISSILE GUIDANCE, THERMAL IMAGING, NAVIGATIONAL AIDS AND NIGHT VISION. FOR OPERATION IN THE BACK-SIDE ILLUMINATED MODE IT IS REQUIRED THAT THE ACTIVE DEVICE LAYER OF ...

The reliability of electronic packages is of paramount concern in todays electronics industry, and ensuring their thermomechanical integrity is necessary to achieve this reliability. However, this task has become more challenging with miniaturization and the introduction of new materials. Thermal stresses in electronic packages continue to be one of the leading causes of device failure. The pro ...

Current research shows that failures in the standardization process are often the result of a failure of the participants to communicate or organize. To this effect, NIST has developed a tool, NIST Ontological Visualization Interface for Standards (NOVIS), with an environment for visualizing, browsing, and querying standards. Aztera will create a Computer Aided Standards Development (CASD) framewo ...

Incremental system/software integration and the maintenance and evolution of embedded systems are not well supported by current tools. This is particularly true of high-availability systems that can't be shut down to use off-line integration approaches. We have developed a software architecture that associates dynamic integration command statements with the code of the current and new components. ...

We are developing erbium doped fiber amplifiers (EDFAs) for optical communication systems, local area networks, fiber sensors and optical measuring instruments. The EDFA is a new and revolutionary technology that is having a profound effect on the design of lightwave system architectures and other applications. Never has a technology blossomed as fast as the EDFA: it went from a twinkle in the eye ...

One of the most interesting aspects of the new carbon allotropes, the fullerenes, is their versatile electronic properties, which range from insulating to superconducting depending on the type and level of admixtured elements. The record fulleride transition temperatures have been steadily rising and is 45K at this writing. Fullerenes even have advantages over the ceramic superconductors because o ...
