The Johns Hopkins University Applied Physics Laboratory (APL), Laurel, Md., has signed an option to license its solid-state power amplifier technology — originally developed for NASA space missions — to EMS Technologies Inc., Atlanta, Ga. This agreement will enable EMS to adapt the technology to its commercial product line.

Used to amplify microwave communication signals sent from spacecraft to Earth stations, APL's proven, high-efficiency, solid-state power amplifiers incorporate high-reliability microwave integrated circuits and hybrid construction techniques. The amplifier package was designed for ease of production and very low mass and volume while maintaining a good thermal path that allows attached devices to operate at minimum temperatures, thus enhancing their performance and reliability.

"Making this technology commercially available will help lower the government's cost for future deep space missions," says Dr. Joseph Suter, Director of Technology Programs in APL's Technology Transfer Office.

"By capitalizing on the government's prior R&D investments, EMS can deliver enhanced solid state power amplifier products at lower cost," says Nick Fuhrman, Director of NASA Business Development, at EMS' Space and Technology Group in Atlanta.

Engineers in APL's Space Department have developed solid-state amplifier technology over 15 years for use in several space applications. The amplifier is now being adapted to fly in MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging), NASA's latest Discovery mission, managed by APL. MESSENGER is scheduled for launch in March 2004 and to begin orbiting Mercury in April 2009.
