TECHNOLOGY TRANSFER OPPORTUNITY: REQUEST FOR INFORMATION (RFI) ON HIGH SPEED DIGITAL DEMODULATORS This RFI shall not be construed as a request for proposal or as an obligation on the part of the government for any follow-on acquisitions. The government does not intend to award any contract on the basis of this RFI, or otherwise pay for information solicited. All information submitted shall be unrestricted and unclassified. Sandia National Laboratories desires to develop, in accordance with commercial suppliers, advanced, high speed digital modern architecture that will be suitable for satellite communications. It is anticipated that this activity will be pursued under a NO COST Cooperative Research and Development Activity (CRADA). The results of this research will be a universal digital modem architecture capable of operating at greater than 1 Gbps. This architecture shall operate with multiple modulation waveforms including FSK, PSK and various forms of MSK. Development of both the modulation and demodulation sections will be a part of this work. A modem testbed will be used to evaluate various design alternatives. In addition, the architecture developed under this activity must be inherently radiation tolerant and be applicable to satellite communications as well as terrestrial. The architecture, once developed, will be used in the design of a 1 Gbps CHFET modem chip. The modem architecture must be applicable to the type of data path structures used in the GaAs CHFET technology. The GaAs CHFET technology has been developed at Sandia for over 6 years and has been demonstrated in test chips. In addition, the modem architecture must be capable of being implemented in existing high speed DSP chips as well as radiation hardened FPGA designs. Sandia is committed to developing industrial partnerships through a number of mechanisms including licensing of intellectual property, cooperative research and development agreements (CRADAs) and small business assistance programs. Industrial partners interested in pursuing the development of this technology area should contact Sandia's Technology Transfer Office by August 30, 1996. Industrial parties may be required to furnish a commercialization plan and business information for this technology development opportunity.
