DESCRIPTION OF REQUIREMENT:

NUWC Division Newport (NUWCDIVNPT), , has a requirement to replace in-service Phase-Locked Dielectric Resonator Oscillator (PLDRO) units that have a design deficiency, as well as to replace units that fail while in service.

The PLDROs have a 275 day lead time with the required delivery date of 30 March 2023.The total estimated value of this effort is

is the to Ready for Issue condition for the Fleet. In order to meet Fleet demands, the NUWCDIVNPT requires installation of upgraded PLDROs.

A PLDRO is a device which produces a highly accurate and stable Radio Frequency (RF) signal at a frequency. The PLDRO is sub-component of the Raytheon designed and manufactured . provides high capacity communications to submarines in the Frequency and Frequency RF spectrums and is considered to be highly specialized equipment that utilizes unique technology to meet the Navy’s operational requirements.

The PLDRO being procured is an integral part of the with specific requirements for size, weight, power, RF output, environmental survivability, and electromagnetic compatibility. The PLDRO meets all the requisite functional and performance parameters of the , and was designed and manufactured by Ultra Electronics Herley (UEH). UEH is the proprietary owner of the PLDRO design, and is the sole manufacturer of the PLDRO that is currently in place for the design. The PLDRO has the mechanical performance necessary to meet the specifications, as well as the form factor to interface properly with the design.

Under contract N6660420P8499 UEH improved the PLDRO used in the to correct design deficiencies. UEH upgraded the PLDRO from part #14909 to part # 14909-1. The Government does not hold build to print drawings for this custom part.

In order to develop and certify a second source of supply for the PLDRO, would have to certify a prospective design from that second source of supply to ensure all the functional, performance, and environmental survivability requirements of the are
