FWSDR - Software Defined Radio Firmware

  • The edge of technology

    The combination of the firmware FWSDR and the high-end digitizer ADQ14 creates a unique platform for software-defined radio. This 14-bit digitizer provides the high dynamic range needed in an RF environment and the interleaving technology provides high signal bandwidth coverage.

    The interleaving technology is provided through the use of SP Devices’ proprietary technology ADX which removes typical interleaving artifacts and enables the unique combination of bandwidth and dynamic range.

    For digital down-conversion on ADQ7DC and ADQ7WB, please refer to the FW2DDC firmware here.


      The powerful signal analysis in the FPGA on the ADQ14 efficiently reduces the amount of data to be handled by the host PC system:

    • Relaxed data transfer requirements
    • Reduced CPU usage on the host PC
    • Ability to reduce disk storage capacity

      The FWSDR implements a software defined radio in the ADQ14 FPGA for applications such as:

    • RF receiver
    • Satellite monitoring
    • Channel sounder
    Real-time digital down converter (DDC)

      FWSDR contains a DDC:

    • I and Q input
    • NCO
    • Complex mixer
    • Decimation filter
    • Continuous streaming to disk
