Completed TRL 5 (started at 3, targeting 5)
Nuvotronics has developed and optimized the PolyStrataTM process for the fabrication of intricate microwave and millimeter-wave devices. These devices have primarily been rectangular coaxial transmission lines, although rectangular waveguide and other structures have also been demonstrated. Intricate devices have been demonstrated with insertion loss 5 to 10 times lower than traditional planar circuits; isolation better than 60dB for lines that share separating walls; multiple levels of densely-packed coaxial circuits; and low-parasitic attachment to active devices and traditional circuit boards. In this Phase II project, Nuvotronics will optimize and fabricate high density low-loss millimeter backplane circuits to package and interconnect components of future NASA millimeter wave (MMW) radars. The significance of the innovation primarily lies in three areas: reduction of system size, weight and loss in MMW radars. The PolyStrata technology is a batch manufacturing process, providing economies of scale and cost reduction for higher volumes, in addition to flexibility in design for various frequencies of interest.
We anticipate high volume product opportunities within the DOD and non-Government commercial markets. Within DOD, applications in communications and radar systems exist for advanced microwave components. For military communications, the benefits are higher bandwidth, multipoint links, and low payload weight for planes, missiles, and tanks. Programs within the DOD such as the Army's WIN-T (Warfighter Information Network - Tactical) require advanced microwave components in order to meet the demanding applications of satellite communications while on-the-move. Other key market opportunities driving future growth exist in the mobile backhaul, wireless enterprise bridge, wireless fiber lateral emulation, government and public safety networks, WirelessHD, and WiMax.
Our primary goal in this project is to provide NASA with robust space-capable MMW interconnection technology that is lower cost, lower weight, and has improved performance over current technology. The initial application is MMW radars for advanced cloud and precipitation measurements and for Mars landing sensors. Candidate NASA missions are future landers for the Mars Exploration Program and the Aerosol/Cloud/Ecosystems (ACE) Mission. Reducing size and weight of radar instruments will allow more mission capability on each platform, increasing NASA return on investment in these missions. Instrument constraints on size and weight in NASA unmanned aerial vehicles could also benefit from the PolyStrata RF backplane technology as well as future NASA communication systems.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 5) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
