Completed TRL 3 (started at 1, targeting 3)
•In support of NASA’s Ecosystems SAR (EcoSAR) Mission, which is to enable unprecedented two- and three-dimensional fine scale measurements of terrestrial ecosystem and biomass, this project will develop a state-of-the-art (SOA) UHF Band monolithic microwave integrated circuit (MMIC) Power-Amplifier for the EcoSAR instrument’s 32 radar electronics units. This project will significantly advance Power Added Efficiency beyond present day commercial off the shelf offerings operating on the UHF Band, and specifically 335-535 MHz, achieving a TRL 3-4 MMIC power amplifier with over 25 Watts output power, power added efficiency (PAE) of greater than 70%, and power gain of over 35 dB with less than 1 dB gain flatness over the band; consistent with the requirements of EcoSAR. This UHF-band GaN MMIC SSPA performance will be at the very forefront of present-day technology. The efficiency advantages resulting from this project’s custom developed >70% PAE UHF MMIC 25-watt power amplifiers will be multiplied across 32 polarimetric (dual) transmit/receive (T/R) modules which reside inside the aircraft fuselage within a radar electronics unit (REU).
The proposed UHF MMIC capable of PAE >70% will enhance NASA's communication and navigation for SWaP-C conscious applications such as: NASA Mission/Program: Ecosystems SAR (EcoSAR) Electra UHF Navigation Package Mars Perseverance Rover Mars Curiosity Rover
Non-NASA commercial and DOD applications stand to benefit from Recon-RF's advancements in UHF MMIC technology, such as: Tactical Radio (Ground, Shipborne, Handheld) FirstNet Network Commercial 5G New Radio FR1 UHF Air Traffic Control and Wind Profile Radar
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — 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.
