A -- KA-BAND PHASED ARRAY ANTENNA SOL RFP5-59272-235 POC Janet Langweil, Contract Specialist, (301) 286-4212 Darlene E. Walter, Contracting Officer, (301) 286-4239. NASA/GSFC intends to issue a Request for Proposal (RFP)5-59272-235 on a competitive basis for a Ka-Band Phased Array Antenna. The contractor will design, develop, fabricate, assemble, test and deliver one engineering model, one protoflight unit, and associated hardware with options for four additional flight units. The antennas may require new and/or state-of-the-art technology in the following areas: electronic steering and scan performance for communications application; thermal design as related to the antennas operation and survival in spacecraft environment; small satellites, and the constraints that they place on subsystems; semiconductor devices that exhibit a high degree of radiation tolerance; designs that result in minimizing the cost of replicating flight hardware; designs with high reliability that will meet the required operational and storage life; and designs which can be scaled in terms of Effectively Isotropic Radiated Power (EIRP). The contractor will be required to comply with detailed performance and design requirements and specifications and performance assurance requirements. The cost plus fixed-fee contract shall be performed at the contractor's facility. The RFP is scheduled for release in August 1996. All requests for RFPs must be issued in writing to the individual listed above. All responsible sources may submit a proposal, which will be considered by NASA. Electronic versions of the documents will be provided on the World Wide Web at http://genesis.gsfc.nasa.gov/procure.htm, and by anonymous ftp to genesis.gsfc.nasa.gov/public/web/solicita. (0200)
