Broadband Solid-State LINC Power Amplifier Navy SBIR FY2006.2 Sol No.: Navy SBIR FY2006.2 Topic No.: N06-113 Topic Title: Broadband Solid-State LINC Power Amplifier Proposal No.: N062-113-0344 Firm: DataSoft Corp. 7669 S. Myrtle Ave. Tempe, Arizona 85284-1481 Contact: Matt Spencer Phone: (480) 763-5777 Web Site: www.datasoft.com Abstract: Current and future waveforms including those proposed under the JTRS programs contain wideband complex signals. The platforms that deploy these waveforms require high power amplifiers capable of delivering the signals generated by these waveforms without spectral re-growth caused by non-linearity. DataSoft's goal during Phase I is to expand on the proof of concept work done to-date by demonstrating GaN Quadrature LINC at UHF to L-band frequencies. Our solution combines the SWAP benefits of GaN with the linearity benefits of a LINC architecture to produce a power amplifier capable of efficiently producing very high power levels using digital wideband waveforms. Datasoft's JTRS RF design and Digital Signal Processing (DSP) expertise uniquely positions our team to design the next generation power amplifier system for the operation of both current and future complex wideband digital waveforms. Our Phase I research and design efforts will generate a power amplifier system model that is JTRS compliant and satisfies Navy system requirements. Benefits: RF power amplifiers are an integral part of all base stations for cellular infrastructure. They are an expensive component in modern wireless infrastructure equipment, and both their performance and cost are important drivers in base station design. Efficiency, physical size, linearity and reliability are among the principal concerns. As price pressures become fiercer, new and innovative techniques and materials must be used to reduce the cost of this important component part while still maintaining performance. GaN can be a dominant technology vs. currently available alternatives: providing better performance over all the important product specs. Indeed, it may emerge as a disruptive technology, according to market research firms. Return
