- Description
- This preliminary information is being made available for planning purposes only, subject to FAR Clause 52.215-3, entitled ?Solicitation for Information or Planning Purposes.? It does not constitute a Request for Proposal, Invitation for Bid, or Request for Quotation, and it is not to be construed as a commitment by the Government to enter into a contract. This procurement is subject to review or cancellation at any time. NASA/GSFC is hereby soliciting information from potential sources, comments, and inputs concerning the availability, cost, and specifications of a Ka-Band Traveling Wave Tube Amplifier (TWTA) for the Solar Dynamics Observatory (SDO) Project. SDO is the first mission under the Living with a Star (LWS) Program as part of the Sun Earth Connection. SDO will be made up of 3 instruments seeking to characterize the dynamic state of the Sun, thus enhancing our understanding of the solar process and space weather. SDO is viewed as a follow on to the successful Solar and Heliospheric Observatory (SOHO) mission. SDO will be a three-axis stabilized satellite in a circular geosynchronous orbit of ~105?W longitude and having an inclination of 28.5 degrees. SDO will have a mission life of 5 years, and currently, is scheduled for launch in April 2008. SDO will provide a continuous downlink of high rate data (150 Mbps, Reed Solomon and Rate ? Convolutionally Encoded). The transmitted data will SQPSK modulate a Ka-band carrier (26.5 GHz) in the SDO modulator/exciter. The exciter will drive the TWTA, which will generate 5-10 Watts RF into a 0.75 meter diameter reflector antenna (a single output power level will be specified in the final specification). Other preliminary specifications for the SDO TWTA are as follows: 1. Spacecraft bus voltage: 28 +/- 7 volts 2. RF input power: +0 dBm min. 3. RF output power (including output isolator): +37 to +40 dBm min. 4. Output frequency/bandwidth: ~26.5 GHz +/- 200 MHz min. 5. Gain flatness (peak-to-peak) across band: 1.0 dB max. 6. AM/PM: <= 10 degrees/dB 7. Phase nonlinearity across band (peak-to-peak): 3.5 degrees 8. Operational temperature range (baseplate): 0 to +40 C 9. RF input connector: K-female (2.9 mm jack) 10. RF output connector: WR-34 11. TWTA telemetry: internal temperature, RF output power, To Be Determined (TBD) electrical interface 12. Input and output VSWRs: 1.5:1 or better 13. Random Vibration test profile: [PLEASE DOWNLOAD MS WORD VERSION OF THIS NOTICE FOR CORRECTLY FORMATTED TABLES.] 14. Shock requirement: Maximum expected shock environment is as follows: [PLEASE DOWNLOAD MS WORD VERSION OF THIS NOTICE FOR CORRECTLY FORMATTED TABLES.] 15. Parts radiation requirement: Dependent on enclosure material/thickness, with 40 mil contribution from spacecraft. For example, radiation requirement is ~200 krad total dose with a 100 mil thick Al enclosure, or ~20 krad total dose with a 200 mil thick Al enclosure. 16. Parts quality requirement: Quality Level 1 (per GSFC 311-INST-001) parts shall be selected when readily available. For those parts not readily available, Quality Level 2 parts, with additional testing as required by GSFC, shall be acceptable. 17. Total mass: 3 kg. max. 18. Required DC input power: <41 Watts for 5 W RF output, <70 Watts for 10 W RF output NASA/GSFC may contract for up to three (3) flight Ka-band TWTAs. However, in order to accurately specify the requirements of the TWTA, the SDO project seeks feedback from industry regarding the above specifications. Responses from industry that have expertise in providing spaceflight Ka-band TWTAs and associated equipment is encouraged. In addition to the technical questions above, please indicate your company?s relevant history associated with the development of Ka Band space flight or military hardware. Also, feedback regarding any other relevant specifications not mentioned is requested. Are any of the specifications not realistic with respect to today?s technology, a significant cost driver to achieve that performance, or unnecessarily over specified to achieve the necessary performance? All information received will be combined and used for government procurement and planning purposes. Sources are urged to describe their approach in enough detail so that NASA can plan for subsequent proposal opportunities for which proprietary information may be appropriate. Interested offerors/vendors having the required specialized capabilities to meet the above requirement should submit a capability statement indicating the ability to perform all aspects of the effort described herein. Responses must include the following: name and address of firm, size of business; average annual revenue for past 3 years and number of employees; ownership; whether they are large or small; a list of customers covering the past five years (highlight relevant work performed, contract numbers, contract type, dollar value of each procurement; and point of contact - address and phone number). Technical questions should be directed to: Mr. Michael Powers. Procurement related questions should be Ms. Lorrie Eakin. Please advise if the requirement is considered to be a commercial or commercial-type product. A commercial item is defined in Internet "Note A". No solicitation exists; therefore, do not request a copy of the solicitation. If a solicitation is released it will be synopsized in FedBizOpps and on the NASA Acquisition Internet Service. It is the potential offerors responsibility to monitor these cites for the release of any solicitation or synopsis. This synopsis is for information and planning purposes and is not to be construed as a commitment by the Government nor will the Government pay for information solicited. Respondents will not be notified of the results of the evaluation. Respondents deemed fully qualified will be considered in any resultant solicitation for the requirement. The Government reserves the right to consider a small business or 8(a) set-aside based on responses hereto. An Ombudsman has been appointed--see NASA Specific Numbered Note "B". This can be accessed at the following URL: http://genesis.gsfc.nasa.gov/nasanote.html . Responses may be sent via electronic mail, regular mail, or fax (but must be received on or before August 10, 2004), as follows: Ms. Lorrie L.
