MARKET SURVEY - SOURCES SOUGHT SYNOPSIS: The Government is issuing this sources-sought announcement as part of a market survey. The Naval Surface Warfare Center, Crane Division, Spectrum Warfare Department, Airborne Electronic Attack Division is interested in receiving information from experienced Radio Frequency (RF) vendors concerning the design and fabrication of a low-cost, high power/low frequency test and evaluation enclosure to accommodate the test and evaluation (T&E) of Airborne Electronic Attack (AEA) antennas. All interested sources are encouraged to submit company and product literature, references, rough order magnitude estimates, production lead-times, schedule, risk, required Government Furnished Equipment/Material, and any other pertinent information for the Government s consideration. The top-level requirements for the enclosure are cited as follows: 1.Performance Requirements The enclosure shall meet the following requirements: a.Provide high effective radiated power handling capabilities of 75dBm / 45dBw (31.62kW) at a Continuous Wave (CW) duty cycle. (Note: 45dBw is the minimum acceptable high effective radiated power handling capabilities. Increased power handling capabilities (i.e., greater than 45dBw), are desired). b.Withstand heat loads as high as 118˚C (244.4˚F) on any part of the interior surface of the enclosure. c.Be able to handle IEEE spectrum frequency bands HF-Ka, while adhering to electromagnetic compatibility standards. d.Provide air circulation sufficient to provide uniform cooling to the interior of the enclosure while the maximum RF energy ( 45dBw) is applied to the wall(s) of the enclosure. e.Rejection of up to 100KW of heat and capable of maintaining an interior air temperature of 24 C (75.2 F) 4 C (68 F 82.4 F). f.The absorber wall shall be capable of continuously dissipating 25kW of heat while receiving forced cooled air at a temperature of 24 C (75.2 F). 2.Build-To Requirements The enclosure shall meet the following requirements: a.The enclosure shall utilize TDK Inc. anechoic ferrite absorbing tiles (ICM-006 & IB-017) or equivalent anechoic tile material that is of the same composition and size as ICM-006 & IB-017 and meets the performance requirements cited in #1. The ICM-006 & IB-017 or equivalent anechoic ferrite absorbing tile combination must completely cover the entire south wall of the enclosure and 1/3 of the east, west, ceiling and floor of the PRIME. IB-017 anechoic tile or equivalent is to cover the remaining interior space of the PRIME. (Note: If requested, recommended instructions on the installation of the tile shall be provided by the Government to the Contractor. However, utilization of these instructions shall not relieve the Contractor from any of the requirements). b.The enclosure shall utilize a closed-loop forced air cooling system to sink and cool extreme heat from the ferromagnetic anechoic tiles populating the interior of the enclosure. Additionally, the cooling system shall utilize finned chill plates as a method to sink RF energy (heat) applied by unit under test (UUT) to the anechoic material. The closed-loop forced air cooling system, which shall be located behind the interior-mounted tile finned chill plates, must be engineered and built to accommodate the cooling of the anechoic tiles populating the entire interior surfaces of the enclosure. Additionally, the cooling system shall be engineered to maximize reliability to facilitate ease of maintenance. Isolation of any individual section shall not effect circulation or cooling capacity throughout the remainder of the system. Thus, when the UUT is radiating at high power/continuous wave and the beam is focused at any one specific interior location of the enclosure s walls, this isolation will not compromise the cooling systems air flow. In addition, each cooling section shall include readily accessible electronic temperature sensors to be used to instantaneously monitor any chill plate within the enclosure. All electrical connections from each electronic sensor shall be coupled to terminal blocks on one readily-accessible control panel. All system components, (i.e. gauges, sensors, etc.), shall be clearly labeled, using a Government approved method, to match all system-level drawings. c.All finned chill plates shall be securely fastened in place and shall be installed in such a fashion that they may be easily removed for maintenance or replacement. Each chill plate shall be constructed with protruding aluminum fins on the back of each (2 x 2 ) mounting structure, allowing the closed-loop forced air cooling system, as discussed in part 2.b above, to circulate chilled air throughout the enclosures finned chill plates. The finned chill plates shall be of equal uniform dimension and weight and shall be interchangeable to allow for mounting to any location within the enclosure. Provisions shall be made in regards to each chill plate for both removal and installation while populated with tile. If a gap between installed chill plates is required for thermal expansion or maintenance purposes, the uniform gap must be mutually agreed upon between the Government and Contractor prior to proceeding with populating the enclosure with the finned chill plates that have a gap between them. When the complete chill plate and tile assembly is mounted to the frame structure, there shall be less than 1 ohm electrical resistance between each chill plate and earth ground. d.Additional enclosure materials that shall be needed to insure the optimal performance of the PRIME while in use are as follows: forced chilled air blower, heat exchanger, walkway, misc support equipment, etc. e.The PRIME s frame structure shall be capable of supporting high power/low-frequency TDK or equivalent RF anechoic ferromagnetic absorber tiles across all six of the entire interior mounting surfaces, equating to an area of ~1,650.06 sq ft, based upon the interior dimensions of the enclosure (populated with the subject anechoic tile) of 20 3 (Length) 17 8 (Width) by 12 4 (Height). 3.Lab Space & PRIME Structure Dimensions The room in which the enclosure is to be housed is ~ 22 3 (Length) by 19 2 (Width) by 14 4 (Height). The exterior dimensions of the enclosure shall be at least 6 , and at most 1 , from the walls and ceiling of the room in which it resides, except bottom wall running the length of the enclosure as it does not have a wall against it and thus this requirement does not apply. The contractor s PRIME design shall allow at least 1 inch or better spacing between the faraday cage and finned chill plate structures to allow the closed-loop forced air cooling system to circulate chilled air through the enclosures interchangeable finned chill plates. The interior dimensions of the enclosure (populated with anechoic tile) shall be 20 3 (Length) 17 8 (Width) by 12 4 (Height). (Note: Any changes to the dimensions of the PRIME must receive Government approval). The circulation shall be sufficient to provide uniform cooling to all installed plates while a maximum RF energy is applied to the absorber wall. The entrance to the enclosure shall utilize a double door design, with a width of 6 and a height of 7 4 . The entrance shall be at the far right side of the bottom wall of the enclosure. 4.Enclosure Weight Capacity - The total weight of the enclosure shall not exceed 71,864 lbs and shall not exceed the weight distribution requirement of 195 lbs/Sq ft. a.(Note #1: The total weight and weight distribution requirements must take into account a total estimated maximum weight of 3,320 lbs for Government Equipment and/or Units Under Test & personnel (2,440 lbs for the Government Equipment and/or Units Under Test (see #11 below), as well as an additional estimated maximum weight of 880 lbs for personnel, equaling an estimated total maximum weight of 3,320 lbs). b.(Note #2: Contractor shall investigate the possibility of fabricating and installing a subfloor in order to meet the weight distribution requirement of 195 lbs sq ft). 5.RF/Radiation Detection System - The contractor shall supply an RF safety radiation leakage detection system. 6.Interior Fire Suppression System - The contractor shall supply a Class B & C rated fire suppression system capable of extinguishing fires due to flammable liquids as a fuel source and fires due to electrical equipment. 7.High Power Cable Porting and Ducts The enclosure shall allow high power cables to enter the enclosure without causing Electromagnetic Interference (EMI) /RF multipathing ambiguities.
