Background & Purpose The 179th CW/MSC, Mansfield, OH, is seeking to identify capable sources that can provide high-performance, high-channel-density Software Defined Radios (SDRs) to serve as a laboratory baseline for complex electronic warfare algorithms. The Government anticipates a requirement for the Ettus Research (National Instruments) USRP X400-Series (X410/X440) or an equivalent solution that meets the stringent hardware and software interoperability characteristics detailed below. The purpose of this notice is two-fold: To identify authorized commercial distributors and Value-Added Resellers (VARs) capable of supplying the specific Ettus Research brand-name equipment. To test the commercial marketplace to determine if any alternative "equivalent" products exist that can meet the Government's strict phase-coherency requirements without disrupting the existing proprietary software pipeline. 2. Salient Characteristics Whether proposing the brand-name product or an equivalent, the SDR platform must be a single, monolithic COTS device (not a networked cluster of smaller radios) meeting the following specifications: Architecture: Direct RF sampling built upon advanced RFSoC technology (e.g., Xilinx Zynq UltraScale+ ZU28DR-2 or equivalent). Channel Density: A minimum of eight (8) independent transmit and eight (8) independent …
