The Department of Defense, through the Naval Surface Warfare Center Indian Head Division (NSWC IHD), intends to award a sole-source contract to Rohde & Schwarz USA, Inc. for the provision of a Calibration Kit Radio Frequency. This procurement specifically requires a 50 Ohm, 2-port, 1.85mm calibration kit to support high-frequency network analyzers operating up to 67 GHz, which is critical for maintaining the operational capacity of the RF lab following a recent $1.5 million contract aimed at enhancing its capabilities. The selected vendor must deliver the complete calibration kit within 60 days of contract award to the NSWC IHD location in Indian Head, Maryland. Interested parties must respond by July 28, 2025, at 10 AM (EST) and direct their inquiries to Shannon Wooten at shannon.cloud-wooten@navy.mil, ensuring they are registered in the System for Award Management (SAM).
