SBIR-STTR Award

The U.S. military''s next-generation radio system, Joint Tactical Radio System (JTRS), is based on Software Defined Radio (SDR) technology and will create new opportunities, methods, and applications for generating and sharing tactical data. To realize the JTRS vision, a universal RF transceiver, capable of implementing the complex communications waveforms of today and tomorrow, is required. A truly universal RF transceiver platform has unique design challenges, and unlike the familiar wireless handset, cannot be optimized for a specific mobile application. DataSoft has identified a new generic transceiver architecture using a high intermediate frequency (IF) design. A wideband local oscillator is needed for this new architecture. Our Phase I activities will develop a functional wideband local oscillator prototype which incorporates new digital and RF technologies from both commercial and Government sectors.

The U.S. military''s next-generation radio system, Joint Tactical Radio System (JTRS), is based on Software Defined Radio (SDR) technology and will create new opportunities, methods, and applications for generating and sharing tactical data. To realize the JTRS vision, a Universal RF Transceiver (UT), capable of implementing the complex communications waveforms of today and tomorrow, is required. In Phase I, DataSoft created a new generic transceiver architecture using a high intermediate frequency (IF) design. In Phase II, we design, develop, and integrate a wideband UT platform with lower power consumption and cost than existing radios. Its RF performance will be verified using a test waveform indicative of the JTRS waveforms (WNW, EPLRS, SRW) used on the JTRS GMR and JTRS HMS programs.
