- Description
- 1. This is a special notice open to U.S. industry requesting information on technologies available in the next one year to provide new or enhanced power amplifier (PA) linearization methods for Airborne Electronic Attack (AEA) weaponry. The Naval Air Warfare Center Weapons Division (NAWCWD) is interested in reviewing the state-of-the-art and emerging technologies application to PA linearization techniques and architectures. 2.The objective of this request is to identify broadband, high dynamic range approaches to PA linearization across the electromagnetic spectrum from the VHF to millimeter-wave frequency range. Quantitative, case-specific measures of a technique's linearization effects such as third-order-intercept augmentation, increased power amplifier efficiency, and increased spur-free dynamic range are of interest. The salient strengths and weaknesses of each technique, especially as related to low size, weight, and power (SWaP) implementation, are also of particular interest. 3.Background: Recent advances in digital technology allow for extremely broadband, low SWaP signal generation in jamming systems. However, the extremely broadband potential of new signal sources is not well-complemented by current PA technologies. In spite of significant advances in tube, hybrid and solid-state PA technologies, Pas are generally the "bottleneck" component to a system in terms of bandwidth, added distortion, and SWaP considerations. Recent advances in the field of PA linearization hold promise in significantly improving on all three of these parameters for specific PA architectures. 3.1Department of Navy applications for this technology include, but are not limited to, standoff jamming (electronic attack) and self-protect jamming (electronic protect). 4.Information desired: 4.1Technical approaches and system concepts to perform PA linearization and the technical maturity of the approaches and concepts. 4.2The size, weight and power, processing and radio frequency and circuit requirements and open architecture characteristics of the approaches. 4.3How linearizer algorithms and hardware can be integrated with existing transmitters systems. 4.4Methodologies from which linearization methods and system performance can be quantified and verified (measures of effectiveness (MOEs), standards, comparisons against conventional techniques, etc.). 4.5MOEs of the linearizer on arbitrary external input signals. 4.6Impact of varying transmitter load characteristics, including aperture effects, upon the linearizer performance. 4.7Linearizer operation impact upon signal characteristics, e.g. doe the linearizer impart a modulation upon the signal. 4.8Impact of transmitter blanking upon the linearizer operation. 4.9System delay, insertion loss, instantaneous bandwidth and power handling. 4.10Methods for linearizing Active Electronically Steerable Array transmitters. 5.This notice is not to be construed as any type of request for proposal. The Government does not intend to award a contract on the basis of this request or to otherwise pay for the information solicited except as an allowable cost under other contracts as provided in FAR Subpart 31.205-18, Independent Research and Development and Bid and Proposal Costs. Any responses received will not be used as a proposal. 6.Submissions will be considered up to and including SECRET. Companies are to adhere to the National Industrial Security Program Operating Manual (NISPOM) procedures for the transmittal of classified responses. Company responses are to include a name and telephone number of a point of contact having the authority and knowledge to clarify responses with Government representatives. Companies are not limited to a single response. Submissions are due 9 Sept 2011 by 12:00 PDT and may be made by mailing your response on a compact disc and one original and three hard copies to: Outer Wrapper COMMANDER NAWCWD 685300E/EDAC 575 "I" Ave. Suite 1 Point Mugu, CA93042-5049 Inner Wrapper NAWCWD Code 45P100E Building 3008, Room 316 Attn.: Dr. Justin Henrie, (805) 989-5453 Point Mugu, CA 93042-5049 7. This notice is part of the Government ™s market research, a continuous process for obtaining the latest information on the "art of the possible" from industry with respect to their current and projected abilities. The information collected may be used by the Government to explore future strategies for EW capabilities. Information received as a result of this request will be considered as business sensitive and will be protected as such. Any proprietary information received in response to this request will be properly protected from any unauthorized disclosure. If respondents wish Government support contractors to sign a non-disclosure agreement, please include the form in the response. The Government will not use any proprietary information submitted to establish the capability, requirements, approach or solution so as to not inadvertently restrict competition. 8.Only U.S. companies doing business in or based in the U.S. will be permitted to respond to this Request for Information. Reponses to questions from interested parties will be promptly answered and provided equally to all interested parties. Any questions that involve the release of proprietary information (or that answer addresses a question peculiar to a company or that company's possible solution) must be submitted in writing to the technical point of contact (TPOC) for review and would be answered in general terms as determined by the TPOC. 9.TPOC is Dr. Justin Henrie, Avionic Engineer, email justin.henrie@navy.mil, phone (805) 989-5453. 10.Secondary POC is Jennifer Barneby, Contract Specialist, email jennifer.barneby@navy.mil, phone (805) 989-7355.
