- Description
- The Federal Aviation Administration (FAA) is requesting information concerning capabilities to manufacture approximately 11,000 Low Noise Amplifier (LNA) units in accordance with FAA's salient characteristics. The LNAs are the first stage of the amplification to an L-Band radar receiver. The LNAs are used in support of the Air Route Surveillance Radar 4 (ARSR-4) Long Range Radar System. Salient Characteristics are as follows: 1.0 SCOPE This specification describes a solid-state Low Noise Amplifier, which is to be used as the first stage of amplification to an L-Band radar receiver. 2.0 REQUIREMENTS 2.1 GENERAL The LNA assembly is used on each of the 23 azimuth assemblies for the receive target paths, and in the receive weather and receive reference paths to provide a 23 dB gain to the receive signals. 2.2 ELECTRICAL REQUIREMENTS 2.2.1 FREQUENCY The unit shall be capable of operation within specified limits over the frequency range of 1250 to 1400 MHz. 2.2.2 GAIN The unit will have a gain of 23 dB, with a deviation no greater than 0.5dB 2.2.3 INSERTION PHASE The insertion phase of S21 should be 165 degrees, with a deviation no greater than 5 degrees. 2.2.3 VSWR The maximum VSWR @ J1 is 1.32:1. The maximum VSWR @ J@ is 1.3:1. 2.2.4 CURRENT DRAIN The maximum current drain on the +20 VDC supply is 250 mA. The maximum current drain on the ?20 VDC supply is 20 mA. 2.2.5 ON/OFF RATIO The on/off gain ratio should be greater than 45 dB 2.2.6 NOISE FIGURE The noise figure of the unit should be no greater than 1.2 dB 2.2.7 INPUT POWER REQUIREMENTS The power available to the amplifier shall be +20 VDC, ?20 VDC, and 5 VDC including line and load regulation. 2.2.8 COMPRESSION POINT The 1dB compression point should be greater than ?10 dB. 2.2.9 SWITCHING TIME Turn on time must be less than 1.5 usec. Turn off time must be less than 5 usec. 2.3 MECHANICAL REQUIREMENTS 2.3.1 SIZE Physical size of the unit shall be as shown in figure 1, which will be furnished at a later date. 2.3.2 EXTERIOR SURFACES The exterior of the unit shall be plated or finished to meet the environmental requirements specified in paragraph 2.4.3. 2.3.3 MOUNTING This area is being redesigned and will be available prior to issuance of SIR. 2.3.4. CONNECTORS 2.3.4.1 J3 INPUT POWER CONNECTOR Power is applied through connector J1. The part number for the J3 connector is MS3102A14S-6P. The pin out for the connector is as follows: PIN 1 +20 VDC 2 Positive TTL control 5 -20 VDC 6 +20 VDC Return 7 Negative TTL control 9 -20 VDC Return 2.3.4.2 J2 LNA OUTPUT The RF output signal leaves the unit at J2. The J2 connector is a female N-Type receptacle. 2.3.4.3 J3 LNA INPUT The RF input signal is applied to the unit at J3. The J3 connector is a female N-Type receptacle. 2.4 RELIABILITY AND MAINTAINABILITY 2.4.1 RELIABILITY The unit shall have a minimum mean time failure between (MTBF) of 20,000 hours. 2.4.2 ELECTROMAGNETIC INTERFERENCE The design of the unit shall be such that it can perform its operational function in the high power radar environment. There shall not be any interference to radar performance from the unit. 2.4.3 SERVICE CONDITION The unit shall be designed to operate with ambient temperature between -10oC to 50oC and with a relative humidity from 5% to 90%. Vendors must respond with questions and comments directly to Mark McFarland, Engineer, at Mark.McFarland@FAA.gov with a copy to Cheryl Martin, Contracting Officer, at Cheryl.D.Martin@FAA.gov. Mark responses to this market survey with Market Survey File #02-01, to arrive by June 18, 2002. Facsimile responses are not permitted. The FAA will not pay for any information received or costs incurred in preparing responses to this market survey. Any proprietary information should be so marked. This request for information shall not be construed as a request for proposal or as an obligation on the part of the FAA to acquire these items. Responders to this market survey may be asked to provide additional details/information based on their initial submittal.
