W and V Band Satellite Transceiver

Description:

OBJECTIVE: Develop satellite transceivers with W-band (81-86 GHz) uplink and V-band (71-76 GHz) downlink capability. DESCRIPTION: Demand for military satellite communication capability and bandwidth continues to increase. The current state-of-the-art for high-bandwidth satellite communication utilizes Ku and Ka-band frequencies. To avoid growing congestion at the Ku and Ka frequencies and to access a much broader spectrum, the Air Force is exploring the potential of operating satellite transceivers (also called transponders) in the W and V frequency bands. These much shorter millimeter wavelengths introduce unique technical challenges and opportunities. A disadvantage is the considerable uncertainty regarding channel propagation characteristics at these frequency bands. Potential advantages include recent advances in space qualifyable processors and millimeter-wave amplifier electronics. The fundamental purpose of this research topic is to mitigate key technology risks to enable development of future satellite communication architectures using W-band (for uplink) and V-band (for downlink). This technology is intended to support future high-bandwidth satellite (geosynchronous) to-ground communication. The specific field-of-study for this research is satellite communication (i.e., link analysis, encoding and decoding, transmission and detection, channel propagation effects, and electronics). The specific technology need addressed by this research topic is design and development of a satellite W/V-band transceiver. Innovative designs and/or research activities are solicited to support development of a satellite W/V-band transceiver. Successful phase 1 and phase 2 efforts will provide tools and/or mature technologies to facilitate transceiver development. Proposers must demonstrate an understanding of satellite transceiver design, systems engineering, and implementation issues. The technical merit of a proposed transceiver concept or research activity must be demonstrated with respect to requirements resulting from a link analysis and should address a key technical risk or design problem. An optimal transceiver design concept should minimize key performance parameters of size, weight, power, and cost, while maximizing transceiver performance (capacity, flexibility, and availability). The uplink frequency band is limited to 81 86 GHz, and the downlink frequency band is limited to 71 76 GHz. The design is not constrained to off-the-shelf components or space-qualified components. It should be assumed that the transceiver would be integrated onto an existing communications satellite spacecraft and bus. The contractor can make reasonable assumptions for the design of the companion ground transceivers. PHASE I: The phase 1 effort must examine the many design trades available (i.e., power, aperture, channel bandwidth, electronics) and implementation risks. The phase 1 effort should identify key technology risks and design uncertainties, and develop mitigation strategies to address those issues in a phase 2 effort. PHASE II: The phase 2 will focus on mitigating key technology risks identified in the phase 1 effort through software or hardware development, testing and demonstration. The phase 2 should result in an understanding of the key performance parameters and achievable performance for a practical realization of the revised transceiver concept. PHASE III: Phase III Dual Use Applications: Military Application: MILSATCOM systems would benefit from high capacity satellite uplink / downlink capability at W-band and V-band. Commercial Application: There is growing commercial interest in W-band and V-band for terrestrial wireless communication. REFERENCES: 1.
