Wideband Multi-Carrier Digital Up-Converter

Welkin Sciences proposes to design and build the Direct L-band Converter (DLBC), which not only includes the digital up-converter (DUC) function needed by the Warfighter Information Network-Tactical (WIN-T) program, but also provides two very important additional capabilities that go beyond the functionality solicited by the SBIR A10-016 topic description. First, the L-band 950 MHz to 1950 MHz frequency range will be extended to 2000 MHz so that our proposed DLBC design will support both the WIN-T program and the Modernization of Enterprise Terminal (MET) program. Second, our proposed DLBC design will also include a digital down-converter (DDC) function, thereby allowing both directions of digital signal data defined by the fiber optic interface specification to be operational in the first hardware implementation. Therefore, a latter redesign of the DLBC to add the DDC capability (implicitly envisioned by the solicitation) will not be necessary.
