Single Source Justification (Simplified Acquisition)

This document is a Single Source Justification for a simplified acquisition by the Air Force Test Center (AFTC/PZZ) under the Stingray program. The contracting activity seeks to procure 20 units of Model DF9965 2.2–5.15GHz SMA Dual Junction Radio Frequency Isolators from DiTom Microwave, Inc. The purchase request identification number is F150AY6086A002 / ACQ-26-H27, with the estimated contract cost redacted. The isolators are required to support Flight Test Re-Radiation (ReRad) systems for the 420th Combined Test Force, specifically to support real-time Weapon Re Radiation during weapons carriage testing of various assets on test aircraft at Edwards Air Force Base.

The justification for single-source procurement centers on strict airworthiness and configuration control constraints specific to Northrop Grumman-furnished test aircraft. DiTom Microwave is identified as the sole approved OEM capable of supplying the required isolators, which are integrated into Government Furnished Equipment (GFE) per the original engineering drawings (X2017588RC). The document emphasizes that any substitute or alternative part number is strictly prohibited due to airworthiness certification requirements, as using unapproved components would render the aircraft unsafe and violate flight certifications. No other vendors are capable of manufacturing this highly customized component, and DiTom Microwave holds proprietary rights to the design and configuration control documentation. The government will continue market research efforts to identify alternative sources for future procurements.
