MaXentric proposes the GAU2x2 wideband power amplifier system. The design combines MaXentric’s wideband RF PA technology with advanced digital signal processing in a single small footprint package. This tight integration is made possible through the extremely high efficiency and low power dissipation. Since very little power is dissipated as heat, the package and heat sink size can be minimized. ...

Special Operations Forces (SOF) currently must carry multiple power amplifiers and associated batteries for all required communications equipment to conduct their missions.These portable power amplifiers and batteries add weight, heat, and bulk to an already burdened SOF operator.Technology advances have realized incremental improvements in each of these three factors but an ideal innovative solut ...

In this Phase II SBIR program, Southwest Sciences will continue the development of small, low power instrumentation for real-time direct measurement of carbonyl sulfide (OCS) in the atmosphere, especially targeting airborne measurements. The instrument is based on a room temperature interband cascade laser (ICL) operating in the 4800 - 4900 nm region. This laser has a substantially reduced (by a ...

The STTR topic T5.01 envisions Autonomous Communications Systems (ACS) that can be aware of RF environment and the network status and learn from experience to enhance adaptability to nominal/anomalous conditions, self-reconfigure network connections, dynamically maximize performance in response to sensed conditions and mitigate system-level effects of outages and interference. In Phase II, Bluecom ...

We propose to develop a Photon-Counting Integrated Circuit (PCIC) detector and focal plane array (FPA) with highest sensitivity, lowest noise and hence highest signal-to-noise ratio (S/N) among all FPAs covering the shortwave infrared band, for incorporation into a prototype imaging spectroscopy CAMM instrument for real-time operation on a planetary surface to guide rover targeting, sample selecti ...

Atmospheric clouds have strong impact on the global radiative budget. Cloud's radiative properties are strongly affected by droplet size distribution and number concentration. This SBIR project will develop an innovative, compact and inexpensive droplet measurement system (DMS), which will provide in situ measurement of droplet size distribution function and droplet number concentration in clouds. ...

New classes of aircraft, providing personal, on-demand mobility, are under development and are poised to revolutionize short-duration air travel.nbsp; The impetus for this work comes from advances in electronics and controls, and increases in electric motor power densities.nbsp; As these aircraft are integrated into the transportation system, they will encounter icing conditions that may challenge ...

Interest in Unmanned Aircraft Systems (UAS) for civilian use has increased greatly in recent years and is expected to grow significantly in the future. NASA is involved in research that would greatly benefit from advancing the ability of UAS to make autonomous real-time decisions based on sensor data. This SBIR effort will provide this capability, developing and demonstrating an intelligent cont ...

Operating costs and fossil fuel consumption of civil transports can be reduced through use of efficient counter rotating open rotor (CROR) propulsion systems, thereby addressing both key industry needs and long-term NASA technical goals. To develop such next-generation systems, multiple design variables must be assessed efficiently within a conceptual design software environment. A blend of phy ...

Radiation tolerant, extreme temperature capable electronics are needed for a variety of planned NASA missions. For example, in-situ exploration of Venus and long duration Europa-Jupiter missions will expose electronics to temperatures up to 500 ?C and radiation of 3 Mrad (Si) total dose. During this program, United Silicon Carbide will extend the capability of its SiC JFET integrated circuit (IC) ...
