Description

EXTENSION OF REQUEST FOR INFORMATION (RFI)/ SOURCES SOUGHT (SS) NOTICE LIGHTWEIGHT TRANSPORTABLE SATCOM ANTENNA SYSTEM TO FEBRUARY 3RD 2006 THIS IS A REQUEST FOR INFORMATION (RFI) AND NOT A SOLICITATION. The US Army Research, Development and Engineer ing Command (RDECOM), Communications Electronics Research, Development and Engineering Center (CERDEC), Space and Terrestrial Communication Direct orate (S&TCD) is requesting information from companies that have design/development experience in antenna sys tems and/or power amplifiers for vehicle-mounted Satellite Communication (SATCOM) systems in the X, Ku, Ka and Q bands. The Government wishes to de termine potential sources for the development of an affordable, lightweight Comm-On-the-Halt (COTH) multiban d antenna system for tactical satellite communications. INTRODUCTION: It is desired that next-generation multiband, transportable COTH antenna systems operate with an increased data rate, while being lighter in weight and potentially smaller than cur rently fielded systems. Ease of use and setup are also highly desired qualities. This antenna system should be capable of transmitting and receiving via multiple commercial and military satellite systems, including the Wideband Gapfiller Satell ite (WGS), commercial Ku Band systems, XTAR, Advanced EHF (AEHF), and Tr ansformational Satellites (TSAT). If easily accommodated, commercial Ka Band systems may also be of interest. Simultaneous links to more than one satellite are not required. The Government is requesting information from Industry to aid in determining the maturity of key technologies to meet these requirements. It is understood that novel or alternative approaches to the problem may be needed to meet the desired object ives. P ossible alternative approaches could include, but are not limited to: shaped dual reflector systems for increased aperture efficiency, bifocal reflectors with two multiband feeds to eliminate manual feed changes, and the incorporation of an additional agi le scan capability (either electronic or mechanical) with limited field of view to assist with antenna pointing. This information will assist the Government in formulating an acquisition strategy and associated timeline for development of a future antenna program. The Government plans to start development of a multiband antenna system in FY07, with an OTM demonstration on Army representative vehicles in FY08 to validate a Technical Readiness Level (TRL) 6. Key areas of intere st for this antenna system in clude TWT (Traveling Wave Tube) amplifiers size/power and reliability. SCOPE: The purpose of this RFI is to gather information to support a possible RFP release for a multiband COTH SATCOM TWT amplifiers, and to determine Industry interest in participating in this effort. The Government will use the information gathered in re sponse to this RFI to gain an understanding of potential approaches to meet COTH SATCOM TWT amplifier requirements. We seek to understand the current state of development that companies have achieved in TWT amplifier designs, as well as various alternative innovative and creative solutions, and how these might apply to the Government effort to achieve a lightweight, affordable, efficient COTH antenn a system to potentially replace the HC3 COTH Phoenix. DATA SUBMISSION REQUIREMENTS: Key areas of interest for this antenna system and amplifiers include the following items. Please address as many of the following as possible in your Information packag e: 1. Statement of interest, either as a Prime- or a Sub-contractor/partner/team member. 2. Description of qualification: Demonstrated Products, Projects, Applicable experience. State whether your current experience is in design, deve lopment or both. 3. Description of existing or planned multiband COTH antenna systems: - Antenna efficiency and size (deployed and stowed volume) - Simultaneous feed design or auto/manual feed change - Antenna controller - Acquisition/ Tracking methods - Total system size, weight, and power requirements 4. Weigh t estimates for antenna/positioner systems for 1.2m, 1.8m and 2.4m diameter antennas. 5. Technologies or approaches for lightweight, large aperture (1.2-2.4m) antennas operating in a high wind environment. 6. Feed technologies or approaches to mitigate setup complexity. For reflector-based approaches, a minimum number of feeds are desired to cover the listed frequency bands. Approaches that do not require manual changing of feeds are also desirable, as are smaller, lightweight feeds. For small feeds that may have wider beamwidth (~120 degree 10 dB beamwidth), comment of the feasibility of associated reflectors for this application. 7. Applicability of the aforementioned technologies to a 2.4m X/Ka band transit-case terminal. 8. Description of existing or planned feed-mounted COTH amplifiers at X-, Ku-, Ka- and Q-band with RF power at 1dB gain compression for 75W-100W, 150W-200W and 250W-350W (except Q-band): -Amplifier power and efficiency -S ize and weight -Effects of vehicle vibration and temperature of lifetime 9. Description of existing or planned multi-band amplifier design -Ka/Q, X/Ku, Ku/Ka 10. For TWTs and SSPA, describe existing or planned line arization technology for improved performance with linear modulation schemes 11. Description of solid-state-power-amplifier (SSPA) and TWT hybrid solutions for reduction of size and weight. 12. Risks and risk mitigation strategies. 13. Costs: Methods for setting and achieving realistic cost objectives. What capabilities/ components are expected to be the major contributors to the cost? What is the estimated cost for the development of a pre-production prototype? DESIRED CHARA CTERISTICS of the SATCOM COTH ANTENNA SYSTEM include, but should not be limited to: 1.
