D -- SHIPBOARD UHF RADIO DIGITAL WIDEBAND TRANSMISSION SYSTEM (DWTS) POC Matthew E. Brandt, PMW 172-12B, 703-602-8279 or Linda Squires, 02-32, 703-602-0660. Synopsis No. 25. Space and Naval Warfare Systems (SPAWAR) is seeking detailed information concerning an Ultra High Frequency (UHF) multichannel full duplex radio system with digital wideband transmission capabilities for maritime application. Current interest is that the UHF radio system be able to process conditioned diphase signals, use binary modulation, interface with a wideband encryption device, and have a frequency range covering two UHF frequency range bands, which are 225 - 400 MHz, and 1350 - 1850 MHz. In addition, the radio system must be compatible and selective from a menu of data rates, such as T1 (1544 kbps), EUROCOM (256/512/1024/2048 kbps), ATACS (288/576/1152/2304 kbps), and TRITAC (256/512/1024/2048 kbps). In addition, the system primary power requirement is 115 VAC, 50/60 Hz, single phase power. The system should be easily maintained and operated. Also, it should feature a full remote control capability using a remote computer terminal and optimized for network operation. Information submitted should include all available White Papers describing: 1) details of the UHF multichannel radio system design, 2) testing and reliability data, 3) delivery and cost data. Please note that this is a Request For Information only, and that no procurement documents for such a radio system exist at this time. SPAWAR may, however, use information obtained through this request when structuring future NDI/COTS procurement documents which may include a requirement for demonstration of the proposed radio system prior to award of any future contract. Interested parties should indicate whether they are small business, small disadvantaged business, or 8(a). This is not a request for proposal (RFP), a promise to issue an RFP, nor a promise by the government to pay for information received in response to this synopsis. Acknowledgement of receipt will not be made nor will telephone inquiries be honored. Proprietary data submitted in response to this synopsis will be protected when designated. A procurement, if any, resulting form this synopsis will be separately synopsized by RFP in the CBD.Interested offerors may send information by 23 February 1995 to: Commander, Space and Naval Warfare Systems Command, Attn: Matthew E. Brandt, RF Systems Engineer, Code: PMW 172-12B, Room 540, 2451 Crystal Drive, Arlington, VA 22245-5200. Please reference this synopsis no. 25 on both mailing envelope and the enclosure. (0053)
