About this file
This document is a Statement of Work (SOW) from the Joint Navigation Warfare Center (JNWC) for high power cables and POFA equipment. The JNWC requires 58 coaxial cables and 40 connectors specifically designed for high-power jamming environments with precise electrical and mechanical specifications. Key technical requirements include the ability to amplify RF signals between 800-2000 MHz, handle up to 3300W maximum power (2000W sustained), and maintain maximum line loss of 4.3 dB/100ft.
The solicitation (FA9401-25-Q-0013) is issued by the Department of the Air Force Materiel Command Nuclear Weapons Center and focuses on cables and connectors for the NEMISys system used in navigation warfare operations. The cables must support specific frequency ranges, including 1575.42 MHz and 1227.6 MHz signals at 1500 watts, and be robust enough to operate in extreme environments. The ultimate goal is to enhance the test environment's efficiency by minimizing power loss during signal transmission for Global Navigation Satellite System (GNSS) interference signal tests and exercises.

STATEMENT OF WORK
TITLE: High Power Cables/POFA Equipment
Requiring Activity Name: Joint Navigation Warfare Center (JNWC)
1.0 OVERVIEW
1.1 BACKGROUND
1.2 SCOPE
JNWC has a requirement to transmit high levels of power for certain objectives during POFAs and FTXs. To be able to achieve this objective the JNWC needs cables and connectors that can handle the power that the 1500-watt amplifiers in the NEMISys are producing and effectively transfer it to the antennas. This must be done with the least amount of power loss through the cables as possible to increase efficiency, ultimately resulting in a better test environment. These high-power cables must also be flexible and rugged for the extreme environments the NEMISys are operated in.
1.3 OBJECTIVE
The JNWC’s is looking to acquire 58 coaxial cables and 40 connectors with the requirements listed below, in order to equip our NEMISys for high power jamming environments. Various cable lengths and connector types are required and are also listed in the requirements section below.
2.0 REQUIREMENTS:
• Electrical o Must be able to amplify 800-2000 MHz RF signal.
o Must be able to amplify 1575.42 MHz signal to at least 1500 watts.
o Must be able to amplify 1227.6 MHz signal to at least 1500 watts.
o Must be able to handle 3300W max and 2000W sustained power o Maximum line loss throughout cable cannot exceed 4.3 dB/100ft, not including connectors.
o Connectors must be able to pass the same frequencies at the same power levels.
