A -- ADVANCED MULTIFUNCTION RF SYSTEMS CRITICAL ENABLING TECHNOLOGIES (AMRFSCET) SOL 97-023 DUE 080197 POC Glynis Fisher 251, ONR (703)696-0993 BAA 97-023.(Part 2) These modules must exhibit a wide bandwidth (~10 -- 20 GHz), high power (e.g., goal of >10W at X-band), low noise figure (<3 dB goal), and high linearity (~28 dB below rated power). Since the size, output power, and efficiency of these modules are highly dependent on the characteristics of the high power output amplifier, a power-added-efficiency of 40% is desired. Low noise amplifiers with high third-order intercept (TOI), low power consumption, and low noise figure are key parameters. If a hybrid approach is considered for the true time delay concept, a low loss phaseshifter/attenuator/switch/amplifier network is desired. Circulators must exhibit low insertion loss with maximum amount of isolation and reflection uniformity to support reduced RCS. Direct Digital Synthesis (DDS) -- The AMRFS system will fully integrate radar, electronic warfare and communications modes into a single integrated RF system. It is desired that AMRFS exciters incorporate DDS technology forall functions. In the near term, DDS may be used to support electronic warfare (EW) functions such as counter-targeting and counter-terminal electronic attack (EA) signal generation, the development of channelized and digital receivers, the implementation of true time delay beam forming, and complex signal generation with arbitrary waveform generators. In order to support the EA functions against coherent threats, a digital RF memory (DRFM) should be considered but is not required. If the DDS is to be used in the future for digital beam steering transmission, the DDS, in conjunction with the digital receiver and memory, should also include the attributes of a DRFM in coherently replicating threat radar waveforms. In the far term, as the speed, resolution and spectral purity improves, DDS and arbitrary waveform generators may be used for synthesizing radar and communications waveforms. The minimum acceptable digital to analog converter (DAC) performance is 12 bits of -60 dBc spur free dynamic range with 1 GHzof bandwidth. Analog to Digital (A/D) Converters -- A/D converters (ADCs) are critical to radar applications in providing enhanced dynamic range to address high clutter environments, and reducing down-conversion stages. For EW, communications, and radar applications ADCs are used to digitize the received waveforms for further processing. The goal of the ADC is to ultimately produce digital receivers with reduced size and weight. The ADC is a critical component which limits current radar and EW performance levels both in the near and far term. For EW applications, the desired demonstrable near-term performance for ADCs is 12 bits of spur-free dynamic range with 400 -- 500 MHz of bandwidth, where speed is more important than resolution. For radar and communications, the desired demonstrable near-term performance for ADCs is at least 20 bits of spur-free dynamic range with 20 MHz of bandwidth, where resolution is more important than speed. Technical approaches that allow relaxation of ADC speed and dynamic range should also be considered. Acceleration of near-term, economical industrial manufacture of devices is of interested and should be verifiable. ONR is particularly interested in technologies that are applicable to shipboard and airborne which do not require open-loop cryogenic operation in the near term, and operate without cryogenics in the far term. True Time Delay -- True Time Delay beamsteering provides wideband simultaneous operation of multiple signals in a phased-array AMRFS antenna. Time delay should be considered where feasible or a combination of time delay and phaseshifting, at the module level and subarray level if necessary to achieve affordable performance, should also be considered. The beamformer should be capable of providing time delay at a subarray level such that instantaneous bandwidths of 1.5 GHz, at a minimum, are supported across the full operating frequency band. In addition, the beamformer should initially support at least 4 simultaneous, independent beams. Ideally, each beam should be fully reconfigurable and be able to access arbitrary portions of the aperture at any time. The microwave loss through the beamformer should not significantly degrade system performance while maintaining system dynamic range and phase noise. Finally, the overall system throughput delay needs to be kept small. Potential for economical fabrication and packaging technique should be verified. Photonics, digital, and hybrid solutions should be considered among others. Dynamic Resource Allocation and Management Optimization (RAM) -- ONR is interested in developing multifunction sensor resource managers for AMRFS, specifically for SC-21, CVX, and CSA mission areas. The RAM should provide scheduling and allocation of shared resources, interconnection of resources into the required configuration, arbitration of functions in case of conflict, testing, statusing, and maintenance of the shared resource pool. The RAM effort should include the following: 1) the determination of mission events for SC-21, CVX, and CSA that drive the requirements for interfaces, resources, interconnections, and equipment; 2) the development of visualization tools to determine under what conditions contentions would occur and to characterize AMRFS; 3) an assessment of multifunction system operation and functionality; 4) simulation and analysis of multifunction system resource utilization; and 5) an assessment of AMRFS testbed system function and resource interaction. White paper responses should include at a minimun but not be limited to: (1) a definition of enabling technologies being proposed for demonstration along with their associated cost and an estimation of cost and performance uncertainty/risk; (2) a description of the demonstration objectives; (3) an assessment discussion of critical issues that must be overcome to achieve the demonstration objectives; (4) a description of how the critical technology will be used to achieve multifunction capability; (5) a discussion of government and AMRFS testbed industry team's accessibility to the technology and (6) a rough cost estimate . Potential offerors can propose any or all of the critical technologies listed in this BAA. Each submission (white paper) however, should indicate only one critical technology area. If several approaches are proposed per technical area, they should be costed separately. An AMRFS CET BAA industry day is scheduled for the 15th July 1997 at the Naval Research Laboratory Auditorium Building 28 from 0830 -- 1200 hours. The objective of this industry day is to answer any questions concerning this announcement.
