58 -- MICROWAVE RECEIVER TRANSMITTER SOL N68936-98-R-0172 DUE 081798 POC Jaime Rios, Contract Specialist, (760) 939-8703, Mary Jacobs, Contracting Officer, (760) 939-6043 The Naval Air Warfare Center Weapons Division, China Lake, CA intends to procure portable microwave transmitters, receivers, and miscellaneous support equipment (Duplex System) using an Indefinite Delivery Indefinite Quantity 3 year contract. The system must transmit and receive full motion video using analog modulation to a minimum of 50 miles. Included within this equipment shall be 1 audio subcarrier and 1 subcarrier capable of handling data at a standard T-1 rate. The transmitters and receivers will be utilized on the Kineto Track Mounts to send data from and to the acquisition site and remote receiving installation aboard the Naval Air Warfare Center Weapons Division Ranges and similarly at other DoD ranges. The equipment must possess the capability of being upgraded to a full digital DS-3 data rate signal with a modulated carrier (the transmitter and receiver must be DS-3 ready). The conversion to DS-3 shall be achievable in the field without the benefit of any additional alignments or tuning required. The Government intends to procure a minimum of 2 each and maximum of 50 each portable microwave receivers and transmitters containing the following specifications. Tuning Range, within one of two sub-bands (7.125 to 7.700 GHz and 7.70 to 8.40 GHz); Channel Selection, synthesized in 1 MHz steps minimum; Transmitter Output Power, greater than or equal to 2.0 Watts (Analog); Transmitter Pre-set RF Channels, 12 minimum (front panel selectable) and user programmable within the specified tuning range; Mountable in a standard 19 inch equipment rack with housing, rack mounting ear kit and telescoping rack slides in standard configuration for each portable receiver; Remote Interface, RS-485 remote front panel programmability via keypad and laptop PC computer (set-up remotely, select channels, frequency, audio subcarrier frequency and level control, T1, output power change and query system status); Subcarriers, synthesized in 5 KHz intervals; Transmit 1st IF, 70 MHz; Receiver 2nd IF, 70 MHz; Receiver IF Output, 70 MHz at +5 dBm for IF repetition; Wideband, front panel switch disables internal sound channels and filters for wideband capability; Video Frequency Response, 0.5 dB to 5.0 MHz, Minimum (Wideband 1 dB to 10 MHz); Modulation Sense, positive and negative, front panel or remotely selectable (Video modulation shall be capable of being inverted via a front panel control and/or remotely); T1 Subcarrier Modulation Type, FSK (Frequency Shift Key); T1 Subcarrier Bit Rate, 1.544 Mbit/s; T1 Subcarrier Line Code, bipolar with B8ZS; T1 Subcarrier Bit Conditioning, conforming to all relevant sections of G.703; T1 Subcarrier Data Derandomizer, derandomize the (1+X6+ X7) coding applied by the transmitter; Antenna Alignment Aids (Audio Tone), an audio tone shall be provided to indicate relative signal strength; Antenna Alignment Aids (Meters), an analog bar graph and/or digital meter shall be provided to indicate relative signal strength, as well as, a digital display to indicate received signal level in dBm. The Governmentintends to procure a minimum of 2 each and maximum of 50 each 2-foot diameter Parabolic Reflectors and Antenna Feeds, a minimum of 2 each and maximum of 100 each "L" Brackets with QuickSet Pan Tilt Heads assemblies and Rack mounting assemblies for the transmitters and receivers. Antenna Reflector, 2 foot diameter parabolic reflector (medium weight/strength for long term serviceability), 7.1 to 8.4 GHz, gain is greater than or equal to 30 dBi; Antenna Feed, 7.1 to 8.4 GHz for use with 2 foot reflector, Dual Linear Polarization, Cross-Pole Isolation greater than or equal to 30 dB, Connectorization is "N" Type affixed to feed (no adapters to "N" type acceptable); Antenna Mount, "L" type antenna mounting bracket using Antenna & Feed Pan-Tilt Head Assembly of medium weight with quick-release adjustments in both axes, mobile. QuickSet Model QGH-1-4-62050-6 with a load capacity of 330 lbs. A control arm, QuickSet Model QGM-1-4-65330-9 for QGH-1. The Government also intends to procure (estimated quantities) DS-3Modems, 100 each; 4 foot diameter Parabolic Reflectors with associated Antenna Feeds and "L" Brackets with QuickSet Pan Tilt Heads assemblies, 20 each; Training, 1 Lot. DS-3 Modem, digital interface signal levels shall conform to ANSI Ti.404, AT&T 728 A & B, and CCITT G.703 and G. 752 Standards, DS-3 Line Rate shall be 44.736 Mbps plus or minus 895 bps, FSK Format; Antenna Reflector, 4 foot diameter parabolic reflector (medium weight/strength for long term serviceability), 7.1 to 8.4 GHz, gain is greater than or equal to 33 dBi; Antenna Feed, 7.1 to 8.4 GHz for use with 4 foot reflector, Dual Linear Polarization, Cross-Pole Isolation greater than or equal to 30 dB. Any associated software shall be year 2000 compliant. All deliveries will be FOB China Lake.
