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. ...

In Phase II, we propose to develop high saturation current photodiodes that will meet the following design criteria: (a) Responsivity > 0.65 A/W, (b) 1 dB compression current > 100 mA, (c) Bandwidth DC to 18 GHz,(d) Wavelength response of 1300 to 1550 nm, and (e) OIP3 of +50 dBm. Three different photodiode designs will be tested for maximum saturation current: Partially Depleted Absorber (PDA), D ...

Scientists have made a lot of efforts to achieve subwavelength imaging or super-resolution imaging with a slab of metal film or layered materials. Generally it is hard to obtain images with resolution finer than the wavelength of light. Layered materials recently were proposed to realize the super-resolution imaging in the near field. In this SBIR program, we will carry out theoretical and experim ...

The technical problem: In the event of a terrorist attack with a “dirty bomb”, there would be an urgent need to distinguish between those who have and have not been exposed to radiation, in order to perform rapid triage. First responders and emergency health workers would require a biological dosimetric test for radiation exposure that is rapid, accurate, and non-invasive. The opportunity: a m ...

This Phase 2 SBIR will develop two core technologies, small DC powered compressors and an oxygen (O2) concentrating systems to produce a Portable Oxygen Generating System (POGS). A technology review and preliminary testing indicate that development of asystem to produce a flow rate of 10-15 liters/minute (LPM) of 60% O2 is achievable. This compact system will provide O2 at this flow rate for up to ...

Presently, a need exists for compact mid-infrared sensors for various combat systems in the 21st century. Systems such as the Future Combat System (FCS) will require remote active multi-spectral sensors with combined capabilities of laser radar, remotechemical detection, and multi-spectral imaging. The mid-infrared spectral region offers enhanced atmospheric transmission, including penetration t ...

Nanonex is successfully finishing the SBIR Phase I project and has developed a unique nanoimprint tool, Voyager-I that offers unprecedented fast operation and excellent nanostructure uniformity over a large area. In Phase II, Nanonex will focus on furtherimprovements, production, and commercialization of the Voyager tool.

COMPACT SOFTWARE PROPOSES TO DEVELOP PHYSICS-BASED MESFET, HEMT AND HBT MODELS AND THEN INTEGRATE THEM INTO OUR COMMERCIAL MICROWAVE NONLINEAR CIRCUIT SIMULATOR, "MICROWAVE HARMONICA." EXISTING EXTRACTION BASED MODELS SUCH AS THE MODIFIED MATERKA AND CURTICE MODELS ARE BASED ON MICROWAVE MEASUREMENT INFORMATION. THE USE OF PHYSICS OR PROCESS-BASED MODELS COMPLETES THE ANALYSIS CHAIN BY LINKINGPROC ...
