The Federal Aviation Administration (FAA) intends to award a single source contract to Mu-del Electronics for the procurement of Radio Frequency (RF) Power Calibrators, which are essential for the Terminal Doppler Weather Radar (TDWR) Transmitter Microwave Assembly. This decision is based on the fact that Mu-del is the only approved source that has been tested for this specific product, and the FAA has an immediate need for these calibrators. The procurement is critical for ensuring the operational effectiveness of weather radar systems, which play a vital role in aviation safety and efficiency.
