A new low power high speed design scheme was developed for GaAs HBT mixed signal circuits. In this new design scheme, most of the transistors are biased in quasi-saturation mode to reduce power supply from 5 V to 3.3 V. Due to electron drift velocity overshoots at low electric field for GaAs material, all the analysis including DC, RF/speed and thermal effects favor the GaAs HBT circuits biased i ...

In this project Fetch Technologies will implement and evaluate a new approach to transforming and normalizing data from multiple heterogeneous sources. In previous work, Fetch Technologies developed and successfully commercialized a system for creating “transformation pipelines”. In a transformation pipeline, a new source (with its own unique schema) can be “dropped” into the pipeline, ...

Miniaturization of propulsion systems for nanosats presents unique challenges which, to date, have rendered such small spacecraft unable to have significant orbit change/control and attitude control capabilities. Under a Phase II SBIR, Flight Work Inc. conducted the preliminary design of a pump-fed micropropulsion system and demonstrated the potential of the technology by developing and characteri ...

Freedom Photonics will develop novel optical gating technologies with the required robustness, size, power consumption and cascadability to support dense optical interconnects, optical routing, and line rate optical signal encryption with improved capabilities. BENEFIT: This Phase II work will improve the efficiency of optical modulators and enable novel all optical transmitters that can encode ...

Freedom Photonics’ technical approach to building a terabit optical router for space applications will be to design the router architecture to maximize the functionality of the components that are indispensable for an optical satellite network operation, while adding additional photonic and electronic blocks to expand the routing functionality to a necessary level. To meet the size, weight and p ...

Frontier Technology, Inc. (FTI), in cooperation with Pratt & Whitney Rocketdyne and D&E Power and Propulsion, will develop tools to better understand the current (and projected) health state of liquid rocket engine turbomachinery. The ultimate goal of the research is the ability to provide real-time health management/monitoring of these devices with the objective of reducing turnaround time, incre ...

The study is formulated around use of system level trade studies for the Booster Penetrator subsystem requirements. The Mission Analysis is defined by the weapon requirements and weapon use scenario. Performance requirements are identified so that the explosive, penetrator, target vulnerability, and guidance candidates can establish a viable set of subsystems that can be consolidated for use in th ...

This Phase-II SBIR proposal proposes the use of a new class of diamond-seeded solid-state material system for the manufacture of virtually all packaged intense heat-generating solid-state electronics in X-band and Ballistic Missile Defense radar components and systems. In this proposal wherein much preliminary (also MDA-funded) work has been demonstrated hitherto by the authors, Gallium Nitride-on ...

The gap between research in numerical methods and popular commercial solvers in CFD and related areas has been gradually widening in the recent past, particularly in the realm of high order accurate algorithms. At HyPerComp we are advancing a suite of high order codes based on the discontinuous Galerkin (DG) technique that can be used in electromagnetics, fluid mechanics, MHD and radiative heat tr ...

Radiative heat transfer is a dominant mode of heat transfer in combustion and propulsion systems as well as for hypersonic flow encountered during planetary entry. Solution of the Radiative Transfer Equation (RTE), which is an integro-differential equation, places stringent requirements on the computational resources as: (a) the radiation depends both on spatial and angular dimensions, (b) radiati ...
