66 -- WATER VAPOR MONITORING RADIOMETER ASSEMBLY SOL RFQ2-36686-SLC DUE 092998 POC Sharon L. Connolly, Contracting Officer, Phone (650) 604-6927, Fax (650) 604-4646, Email sconnolly@mail.arc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/ARC/date.html#RFQ2-36686-SLC. E-MAIL: Sharon L. Connolly, sconnolly@mail.arc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format of Federal Acquisition Regulation (FAR) Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation, quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA Ames Research Center has a need to procure a Water Vapor Monitoring Radiometer Assembly, including antenna, mixer, local oscillator, and intermediate frequency (IF) amplifier, to measure the strength of the 183.3 GHz emission line of water in the Stratosphere. The assembly will be mounted in a window of a modified Boeing 747 SP aircraft and will operate at a fixed elevation angle over the 20 years SOFIA lifetime. The system antenna must be compatible with existing window plug designs for 747 aircraft. It must have a narrow beam and a low side-lobe pattern. It must be compact to fit within the volume (15" long x 10" wide x 10" high) and weight (12 lbs. maximum) restrictions of the aircraft. The antenna assembly must include a electrically activated flip mirror to allow mechanical switching of the input beam between the antenna aperture and a black body reference. The black body reference is not part of this procurement. Antenna specifications are as follows: beamwidth (-3 dB), <1.25 degrees at 183.3 GHz; antenna clear aperture, 5.0+/-0.1 inches; antenna gain at 183.3 GHz, >45 dB; first side lobe, -25 dB or lower; and flip mirror frequency, once per minute or faster. The 183.3 GHz mixer's center frequency should be 183.31009 GHz+/-0.05 GHz. The local oscillator's frequency should be 183.31009 GHz+/-0.05 GHz (direct mixer) or 91.65505+/-0.025 GHz (subharmonic mixer) and its frequency stability should be 1PPM or better. The IF amplifier specifications should be as follows: IF gain, 20 dB minimum; bandwidth (3 dB), 50 kHz or less to 500 MHz or more; output connection, SMA female; and output impedance, 50 ohms. The overall system specifications are as follows: input VSWR ratio, 1.5:1 or less; system noise figure, 10.0 dB or less (double sideband); operating temperature, +10 degrees C to +40 degrees C; DC input power, 15 VDC @ 1.5 amps maximum. Test measurements are required prior to delivery for noise figure, IF amplifier gain and antenna pattern. Deliverables for this procurement are: 1) layout drawing, 2) water vapor monitor assembly, and 3) test data package. The provisions and clauses in the RFQ are those in effect through FAC 97-05. This procurement is a total small business set-aside. See Note 1. The Standard Industrial Classification (SIC) Code and the small business size standard for this procurement are 3829 and 500 employees, respectively. The quoter shall state in their quotation their size status for this procurement. All qualified responsible business sources may submit a quotation which shall be considered by the agency. Deliver to NASA Ames Research, Receiving Section, Bldg. 255, Moffett Field, CA 94035 is required within 180 days after Purchase Order award. Delivery shall be FOB destination. The DPAS rating for this procurement is DO-C9. Quotations for the item(s) described above may be mailed or faxed to the identified point of contact by the date/time specified and include, solicitation number, FOB destination to this Center, proposed delivery schedule, discount/payment terms, warranty duration (if applicable), taxpayer identification number (TIN), identification of any special commercial terms, and be signed by an authorized company representative. Quoters are encouraged to use the Standard Form 1449, Solicitation/Contract/Order for Commercial Items form found at URL: http://procure.arc.nasa.gov/Acq/Forms/Index.html to submit a quotation. Quoters shall provide the information required by FAR 52.212-1 with the exception of (d) and (i). If the end product(s) quoted is other than domestic end product(s) as defined in the clause entitled "Buy American Act—Supplies," the quoter shall so state and shall list the country of origin. The Representations and Certifications required by FAR 52.212-3 may be obtained via the Internet at URL: http://ec.msfc.nasa.gov/msfc/pub/reps_certs/sats/. FAR 52.212-4 is applicable. FAR 52.212-5 is applicable and the following identified clauses are incorporated by reference: 52.222-3, 52.233-3, 52.222-26, 52.222-35, 52.222-36, 52.222-37, and 52.225-3. Addendum to FAR 52.212-5 is as follows: ARC 52.232-93. Questions regarding this acquisition must be submitted in writing no later than September 18, 1998. Quotations are due by 4:30pm PDT on September 29, 1998, to the attention of Sharon L. Connolly and should be mailed to NASA-Ames Research Center, M/S:241-1, Moffett Field, CA 94035. It is the quoter's responsibility to confirm if the Government has received the faxed quotation.
