Frequency Synthesizer Modules

The National Oceanic and Atmospheric Administration {NOAA) Aircraft Operations Center (AOC) instruments, maintains, and operates aircraft in support of a variety of meteorological and oceanographic research projects. One of the primary systems is the Tail Doppler Radar (TOR}, used for in-storm reflectivity and wind field measurements on AOC's WP-30 Orion aircraft. The current TOR system was installed in the mid-1970s using a magnetron based transmitter. It does not have the sensitivity to detect light precipitation and other low reflective targets such as ice crystals. This system is experiencing maintenance and sustainability issues because the magnetrons and high voltage power supplies are no longer manufactured. To reduce or eliminate these deficiencies, AOC is designing a replacement TOR system, which requires a new Receiver Synthesizer. This procurement is for ten (10) Radio Frequency (RF) Synthesizer Modules for the new Receiver.Synthesizer Units~

Objectives

This Statement of Work (SOW) objectives are to improve the longevity of NOAA's airborne TOR and to improve th~ data quality provided for hurricane research. The RF Synthesizer Modules will be used as an integral part of the overall upgrade to the TDRs on NOAA's WP-30 hurricane research aircraft.

Scope

The government expects to receive ten (10) RF Synthesizer Modules that will meet or exceed the specifications laid out in this Statement of Work for the following unit:

Holzworth Instrumentation, RF Synthesizer Module (part number HSM12001B).
