TITLE: High Power Cables/POFA Equipment

Requiring Activity Name:

1.0 OVERVIEW

1.1 BACKGROUND

1.2 SCOPE

has a requirement to transmit high levels of power for certain objectives during To be able to achieve this objective the needs cables and connectors that can handle the power that the 1500-watt amplifiers in the 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 are operated in.

1.3 OBJECTIVE

The is looking to acquire 58 coaxial cables and 40 connectors with the requirements listed below, in order to equip our for high power jamming environments. Various cable lengths and connector types are required and are also listed in the requirements section below.
