66 -- PULSE RF AMPLIFIER SOL NRMAL-700DT DUE 051000 POC Doris Turner, Purchasing Agent, 303-497-3872; FAX: 303-497-3163 E-MAIL: NOAA; MASC Acquisition Management, Doris.P.Turner@noaa.gov. The National Oceanic and Atmospheric Administration (NOAA), Environmental Technology Laboratory (ETL) located in Boulder, CO requires one (1) RF amplifier to be used in a pulse Doppler radar wind profiler (RWP). RWP=92s are highly = sensitive and operate similar to other Doppler radars and produce winds by capturing and averaging clear-air backscatter pulse (coded or non-coded) energy directed nearly vertically, typically through the use of a ground- based planar coaxial-collinear antenna. The required salient features = of the amplifier are: 1) operate at a center frequency of 449 MHz with a minus 1 dB bandwidth of 10 MHz, 2) produce 2 kW peak power at its output port, 3) operate at a duty cycle of up 20 per cent, 4) operate with a pulse length of 0.4 to 30.0 microseconds, 5) utilize RF input pulse rise/fall times of 1.0 to 100 nanoseconds, 6) produce output pulse rise/fall times of no greater than 100 nanoseconds, 7) utilize input RF power of plus 0.0 to plus 30.0 dBm (vendor specified), 8) operate into any load impedance at any phase (to infinite VSWR) with automatic recovery, 9) have a nominal input/out impedance of 50 ohms, 10) produce no more than minus 60 dBc spurious content, 11) produce no more than plus 50 dBc harmonic content, 12) produce no more than minus 110 dBm per MHz interpulse spectral density, 13) have no more than 10 degrees = interpulse phase error, 14) have less than 0.5 dB pulse (chip) amplitude stability, 15) have no more than 0.2 dB pulse-to-pulse stability, 16) have over-temp protection, indication, and automatic recovery, 17) have over-drive protection, indication, and recovery, 18) have TTL RF disable control circuitry and indication, 19) operate indoors in a standard 19 inch electronics rack, 20) operate at temperatures of plus 10 to plus 35 degrees Celsius, 21) operate at humidity levels of 0 to 95 per cent (non-condensating), 22) have simplified maintenance/repair features, 23) have a mean-time-between-failures of no less than plus 90,000 hours, 24) utilize forced-air for cooling, and 25) utilize RF stray radiation prevention measures. The delivery time shall be less than 12 weeks after receipt of order. Proven commercial-off-the-shelf (COTS) units (or nearly so) are highly desired and efforts requiring significant non-recoverable engineering (NRE) costs will likely not be considered. Technical questions can be directed to Scott McLaughlin at 303- 497-6473. Proposals will be evaluated on technical merit as well as price. Interested sources may request a = copy of the RFQ on or before May 10, 2000 either by phone, written, faxed or e-mail. The award decision will be based upon the best value to the Government, with technical merit as well as = price being considered . This announcement is being issued under the Simplified Acquisition Procedures, FAR Part 13. Estimated government cost is between $25,000 and $100,000.
