66 -- AIR COOLED MICROWAVE POWER MODULES POC Flo Martin, Code 1165ZF, 812-854-3689, by e-mail martin_f@crane.navy.mil/Mr. Richard Colvin, Code 1165, Contracting Officer WEB: Click here to download specifications, http://www.crane.navy.mil. E-MAIL: Click here to reach POC, martin_f@crane.navy.mil. The Crane Division, Naval Surface Warfare Center is seeking prospective sources to provide air-cooled Microwave Power Modules (MPMs). The MPMs' requirements are described in the preliminary draft specification at http://www.crane.navy.mil. It is anticipated that 12 MPMs will be required per node and that 16 fully operational nodes plus one (1) prototype node will be required. Spare and pipeline MPM requirements are not known at this time. Requirements for additional nodes in support of other systems are expected. The MPM is to be used as an amplifier driving an element(s) of an active phased array antenna (APAA). In this application the RF output of the MPM will be connected to a circulator serving as a duplexer. MPM designs that incorporate a suitable internal duplexer will be considered favorably. Potential sources must provide a budgetary estimate (closing date for submission of response is COB 12 October 1999) for the manufacture of two (2) fully functional engineering samples, 18 full specification compliant MPMs, and the trade study below. The two engineering samples shall be provided with air-cooled heatsinks. Heatsink fans (110 VAC 60 Hz) shall be furnished with the heatsinks if required. The two heatsinks shall also be usable with the full specification MPMs without modification. A trade study of heatsink and MPM design shall be conducted to thermally optimize the heatsink and MPM combination. The engineering samples shall be provided within 4 months after contract award. Delivery of the 18 full specification MPMs shall begin 6 months after contract award with 4 MPMs delivered per month. Multiple responses from a single source are allowed. Responses shall be limited to 30 pages for the technical portion. Technical information shall include MPM and, where applicable, MPM sub-assemblies design and/or test data. The source shall provide an update to the attached preliminary specification that replaces the TBDs with numerical values for the offered MPM. Design calculations shall be supported with applicable and relevant test data where possible. Test data shall include electrical performance and life test data. Prior experience with achieving the required power added efficiency at or near the required RF frequencies and with the same or higher bandwidth shall be included if possible. MPM specification requirements will be appropriately modified if an integral circulator (duplexer) is incorporated into the MPM. The relevancy of design calculations or data shall be stated if not clearly discernable from its context. MPM performance and/or life test procedures, including detailed measurement procedures for the test requirements of the attached preliminary specification, are encouraged and may be included in the source's response and will not be counted against the 30 page technical portion limit. Please do not furnish data which is irrelevant or that is not applicable to this specification's requirements. Teaming among sources is allowed. Prospective sources must carry at least a SECRET security clearance. THIS REQUEST IS MADE FOR PLANNING PURPOSES ONLY, AND IS NOT TO BE CONSTRUED AS A COMMITMENT BY THE GOVERNMENT NOR WILL THE GOVERNMENT PAY FOR INFORMATION SOLICITED.
