58 -- UHF TRANSCEIVERS -- MULTICOUPLER/COMBINER TECHNOLOGIES SOL N00421- POC Jodi Stark, Code 25421J, Contract Specialist, (301) 342-1825 Extension 165. The Naval Air Warfare Center Aircraft Division, Patuxent River, Maryland in conjunction with the Naval Air Systems Command seeks sources for airborne UHF Multicoupler/Combiner Technologies. The intended application for this technology is to provide several UHF Transceivers simultaneous transmit and recieve capability through 1 or 2 aircraft Satellite Communications antenna(s) in both high and low angle modes of operation or 1 of 4 selectable blade antennas. The minimum requirement for this capability is 4 simultaneous UHF signals to be transmitted and received in the 225 to 400 MHz range. This technology shall also be capable of DAMA operation. In addition to the minimum requirement, it is desired that growth for 1 to 7 additional signals be provided. Primary interest is towards Commercial Off the Shelf/Non Developmental Items technologies which can be quickly and easily integrated into existing aircraft. Full Mil-Spec hardware is not required and commercial technologies will be evaluated for application; however, ruggedization considerations apply. Specific interest is in identification of applicable technologies, integrations, space and weight required, technology limitations (i.e. loss, filtering, interference due to broadband noise and spurious signals emitted from another transmitter, transmission losses, signal reception losses, switching response times, bypasses, Havequick, interference, performance), and identification of requirements imposed by the application of the technology on the integrator of the technology into the aircraft. Current plans include the use of 3 half duplex ARC-187 transceivers and 1 full duplex RT-1273AG transceiver. Available aircraft power is 28 VDC and single/ multi-phase 115 VAC 400 Hz. This is a sources sought synopsis for information and planning purposes only, does not constitute an IFB or RFP, and is not to be construed as a commitment by the Government after information has been received. Firms possessing demonstrated experience and expertise in capabilities should include as a minimum: outline of previous qualifications, general description of facilities, personnel qualifications, and interface descriptions and brochures of candidate devices. Any response should be mailed to the Naval Air Warfare Center Aircraft Division, Contracts, Jodi Stark, Code 25421J Bldg 588, MS32, 47253 Whalen Road, Patuxent River, Maryland 20670 by January 17, 1997. Fascimile response is also acceptable and should be sent to the attention of Jodi Stark, Code 25421J at (301)342-1864. (0337)
