Direct Digital Radio Frequency (RF) Conversion Digital Radio Frequency Memory (DRFM) Navy SBIR FY2013.1 Sol No.: Navy SBIR FY2013.1 Topic No.: N131-006 Topic Title: Direct Digital Radio Frequency (RF) Conversion Digital Radio Frequency Memory (DRFM) Proposal No.: N131-006-0237 Firm: Radio Frequency Simulation Systems, Inc. 2345 North Glassell St Orange, California 92865 Contact: James Struble Phone: (714) 974-7377 Web Site: www.rfss-inc.com Abstract: Advancing technology in Sample/Hold, A/D and D/A technology, coupled with full digital capture, store, delay, modulate and reconstruction, will provide the basis for a new Digital RF Memory where all of the RF components can be removed in place of digital logic and analog devices. Removal of multi-stage RF converters and LO schemes reduces the system complexity, cost, size, weight and power requirements while significantly enhancing the reliability and MTBF. Benefits: Advancement in data rates for RF communications including line of sight, cell phone/data, and in particular satellite communications. Broadening the band increases much needed data bandwidth for commercial applications on limited satellite bandwidths including those used for internet, voice/data, and video entertainment. Lower cost, size, power and higher reliability of Digital RF Memory Systems and other receivers/transmitters. Return
