- Description
- NASA/GSFC plans to issue a Request for Quote (RFQ) for 448 GHz Radiometer. 1. Itemized Components (Typical) The 448 GHz radiometer is a heterodyne system and includes the following components: Antenna (horn) Mixer, subharmonic Gunn Oscillator, 56 GHz Isolator Doubler 1 Doubler 2 IF amplifier Three band passive filter 2. Evaluation Criteria (In order of importance) a. The vendor?s experience in delivering similar systems will be an important factor in order to minimize risk. b. Size: The radiometer MUST be able to fit within an existing drum and share volume with existing radiometers. There is no allowance for system redesign. Components are mounted on a metal plate, supplied by the customer. c. Performance: In order to provide the quality of science needed to justify an aircraft flight mission, the performance must meet certain minimum requirements. d. Cost e. Power consumption: Lower power is better, but not at the expense of size, performance or cost. 3. Documentation: Specifications, operating instructions, operating conditions and limits, and other pertinant information shall be delivered for the components supplied. System and component test results shall also be delivered. 4. Requirements a. Packaging The radiometer must fit within a specific volume in order that it be acommodated into an existing drum shaped sensor head containing other radiometers. Some latitude exists for working around a limited number of projections outside the volume such as SMA connectors. The required volume envelope is shown in the attached drawing, and should be considered as a guide rather than a hard requirement. NOTE: The filter can be located away from the IF amplifier for the 448 radiometer, so need not be included in this volume. b. System Performance i. System Noise Temperature: <4200K ii. Power Balancing: The vendor is responsible for the total system performance. Gunn power must be sufficient to drive the mixer after multiplier conversion, IF amplifier must be sufficient to drive off-the-shelf detectors, etc. c. Antenna Assembly i. General: Electroformed, corrugated, gold plated, integral circular to rectangular waveguide transition that mates with mixer. ii. Mounting: Antenna body shall have cylindrical surface perpendicular to the horn aperture suitable for clamping. iii. Beamwidth: Circular aperture, 4.0 degrees +/-0.1 degree (full width half power) iv. Bandwidth: 28 GHz v. Beam Efficiency: >92% as measured from first null vi. VSWR: <1.4:1 vii. Polarization: single-linear viii. On-axis cross-polarization discrimination over passband: 25 dB minimum. d. IF amplifier i. Size: Must be accommodated within the available volume. Typical size should be 1 x 0.4 x 2.4 inches. ii. Bandwidth: 0.5 ? 14 GHz iii. Gain: ~60 dB iv. Gain flatness: +/- 0.5 dB e. Gunn i. Center frequency: 56 GHz, +/- 2 MHz at 35 C ii. Frequency Temperature Stability 3 MHz/degree C f. Doubler 1 and Doubler 2 i. Voltage biased rather than self biased g. Mixer i. Sub-harmonic to minimize doubler count and LO system complexity. ii. Noise Temperature: ~1700 Kelvins iii. Conversion Loss: ~ 8 dB h. Isolator i. Loss: Should be low, but the value is defined by compatibility of the Gunn power with the doubler efficiency and final LO power to the mixer. i. Filter i. Insertion Loss: 1 dB ii. Passbands: Science desires the following (in GHz): 448.0 +/- 1.4 (1.2 bandpass) 448.0 +/- 3.0 (2.0 bandpass) 448.0 +/- 7.2 (3.0 bandpass) A proposed realistic solution is the following (in GHz): 448.0 +/- 1.3 (1.0 bandpass) 448.0 +/- 3.1 (1.8 bandpass) 448.0 +/- 7.2 (3.0 bandpass) Alternative proposals are welcome. iii. Isolation between bands: 25 dB iv. Temperature range: 23C +/- 10C v. Size: Not included in the 448 volume, but should be about 0.8 x 1.75 x 2.75 inches This procurement is being conducted under Simplified Acquisition Procedures (SAP). The Government does not intend to acquire a commercial item using FAR Part 12. See note 26. The anticipated release date of RFQ NNG08230724Q is on or about 01/24/2008 with an anticipated quote due date of on or about 02/14/2008. All responsible sources may submit a quote which shall be considered by the agency. An ombudsman has been appointed - See NASA Specific Note "B". The solicitation and any documents related to this procurement will be available over the Internet. These documents will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application. The Internet site, or URL, for the NASA/GSFC Business Opportunities home page is http://prod.nais.nasa.gov/cgi-bin/eps/bizops.cgi?gr=D&pin=51 Prospective offerors shall notify this office of their intent to submit an offer. It is the offeror's responsibility to monitor the Internet site for the release of the solicitation and amendments (if any). Potential quoters will be responsible for downloading their own copy of the solicitation and amendments (if any). All contractual and technical questions must be submitted in writing (e-mail) to Pamela Henderson not later than February 14, 2008. Telephone questions will not be accepted.
