A W-band digital communications transceiver will be developed with 5 GHz instantaneous bandwidth utilizing the 71 - 76 and 81 - 86 GHz frequency spectrum recently allocated by the FCC. This project has both military and commercial applications for SATCOM and Point-to-Point digital communications using formats such as 1.25 Gbps and 10 Gbps Ethernet for extremely wideband data and video transmission ...

An X-band digital transmit module will be developed that is suitable for phased-array radar and communications applications. This proposed Phase II SBIR will combine our Phase-I X-band transmit module design with a DBF receiver that Applied Radar is developing through separate (non-SBIR) funding from AFRL. In addition, we will investigate the development of a synthesizer to provide a common LO sig ...

AstroPower proposes to develop a lightweight, high performance, ultra-thin electrostatically bonded GaAs solar cell with an all back contact, zero-grid obscuration structure. The unique design incorporates light trapping, adhesiveless cover slide bonding, and eliminates grid shading. This innovation will increase efficiency and specific power due to the higer open circuit voltage and short circuit ...

THE VAPOR SPACE INSIDE AN AIRCRAFT FUEL TANK EITHER IS OR IS NOT FLAMMABLE (OR EXPLOSIVE) DEPENDING UPON THE PERCENTAGE OF FUEL VAPOR AND OF OXYGEN OF INERT GAS SUCH AS NITROGEN OR CARBON DIOXIDE. IT IS IMPORTANT TO KNOW THESE PERCENTAGES WHEN TESTING THE EFFICACY OF EXPERIMENTAL INERTING MEASURES BY FIRING LIVE ROUNDS AT TEST TANKS; BUT THERE IS NO FAST, CONVENIENT, FIELD METHOD OF MEASURING THE ...

Computational Fluid Dynamics (CFD) is playing a crucial role in the development of the next generation of advanced aerodynamic vehicles, such as the National Aero-Space Plane (NASP). CFD tools are critical to analyze the high Mach number flows typical of these advanced flight vehicles because of limitations on experimental facilities under these extreme flight conditions. However, the validity of ...

Compact Software Inc., a leading software company in development of CAD tools for the microwave industry is proposing to develop a much needed bias-dependent noise model for Heterojunction Bipolar Transistors (HBTs). HBTs are viable candidates for future applications in monolithic microwave integrated circuits (MMICs) where highly accurate linear and non-linear noise models are critical, especiall ...

THERE DOES NOT EXIST TODAY A UNIFIED MEANS OF EVALUATING THE VORTEX INTENSITY BEHIND COMMERCIAL JET LINERS PRIOR TO PROTOTYPE DEVELOPMENT AND TESTING AT FULLSCALE. OVER THE PAST SEVERAL YEARS, DATA AND ANALYTICAL DEVELOPMENTS HAVE PROVIDED MUCH ADDITIONAL TECHNOLOGY WHICH MAY MAKE POSSIBLE THE PREDICTION OF WAKE INTENSITY AND DECAY FROM FIRST PRINCIPLES. THE OBJECT OF THIS INVESTIGATION IS TO DEMO ...

This proposal will address the need for a flexible and agile approach to configuring and managing a JBI without placing excessive burdens on the operators. Phase I of this effort refined and developed the concept of using Force Templates as a mechanism for integrating units and their clients into an infosphere. Phase II will implement a first-generation capability based on these concepts. The prot ...

There is a need for optical crystals, having large nonlinear coefficients and low optical absorption in the mid IR region (2-5 m). Crystals of KTA have shown promise in this application, however, improved optical transmission is still required. The synthesis, crystal growth and characterization of the new materials, KiOSbO4 and KTiONbO4 will be examined. Based on previous experimental data, empiri ...

Phase 2 develops an innovative approach for GPS antijam CRPA antennas using miniature spiral elements to form the array. The technique leverages experience with antijam technology and spiral antenna CRPA development. This combination of technologies and capabilities will result in a small, robust and innovative CRPA antijam solution for small platforms, difficult aircraft installations, helicopter ...
