Software-Defined Radio (SDR) System Integration

The contract seeks integration of two USRP X420 software-defined radios to enable phase-coherent emulation for 5G/6G communications and radar sensing applications, requiring precise synchronization of clock and local oscillator systems across both units. The work includes establishing RF interconnects and antenna coupling configurations to ensure signal integrity and spatial coherence essential for advanced wireless sensing and multi-input multi-output system testing. All components must be engineered for tight timing alignment and minimal phase drift under operational conditions to support high-fidelity emulation of next-generation wireless protocols and radar scenarios. The performance location is specified as Gaithersburg, Maryland, with a submission deadline of July 15, 2026, and the work is classified as a subcontract under NAICS code 334220 for communications equipment manufacturing. The contracting entity is the National Institute of Standards and Technology under the Department of Commerce, emphasizing the technical rigor and standards-driven nature of the project. No set-aside provisions apply, and the focus is on delivering a fully functional, synchronized SDR platform capable of advanced experimental validation in controlled environments.
