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.

NAVWAR

NAVWAR EMI System The system JNWC deploys to transmit GNSS interference signals for tests and exercises

NEMISys

Global Navigation Satellite System A system that uses satellites to provide autonomous geopositioning with global coverage.

GNSS

Radio Frequency The oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency[1] range from around 20 kHz to around 300 GHz.

RF

Decibel a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.

dB

Decibel milliwatts Decibel milliwatts dBM Hertz SI unit of frequency, equal to one cycle per second.

Hz

Megahertz Represents one million hertz. Hertz is the standard unit of frequency in the International System of Units.

MHz

Gigahertz Represents one billion hertz. Hertz is the standard unit of frequency in the International System of Units.
