E-MAIL: Artistine R. Lethcoe-Reid, A.LETHCOE-REID@larc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). One (1) each of a Traveling Wave Tube Microwave Power Amplifier that covers the frequency range from 1.0 -- 2.5 GHz, and is capable of producing 1000 watt minimum output pulsed power. Shall also have the following specifications: Output Power: Minimum output power with 1000 watts (1.0 to 2.5 GHz); Amplifier Gain: Must achieve full rated output power with 0 dBm maximum input power; Gain Variation: Plus/Minus 2.5 dB; RF Pulse Characteristics: Duty: 6% minimum, PRF: 1kHz minimum -250 kHz maximum; RF Rise/Fall: 15 ns maximum (10% to 90%); Input VSWR: 1.5: (typical), 50 Ohms; Load VSWR: 2.0:1 Continuous operating, 50 Ohms; On/Off Ratio: 80 dB; Pulse Drop: Not more than 0.1db; Noise Power: 45 dBm maximum (broad-band); Pulse Quality: 0.2 dB power ripple or less (pulse on); Input Pulse: Standard TTL level, 50 Ohm termination (BNC type connector); Harmonics: 0 dBc maximum at rated output power; Noise and Spurious: minus 50 dBc (not including harmonics). Monitor and Control -- Front panel status monitor (displaying these parameters)- Cathode Voltage, Helix current, Average Forward Power, and Average Reverse Power. IEEE -- 488 interface for remote monitoring of all front panel parameters. External interlock/safety connector. Disables amplifier operation when the interlock circuit is open. RF output sample port (at least 40 dB down from the RF output signal). TWT Protection -- Excessive Helix current maximum, excessive Helix current average, cathode voltage monitoring, collector voltage monitoring, power supply excess temperature, TWT excess temperature, high reflected power (full reflected power without shutdown or damage); Input Pulse protection against excessive pulse width, high duty cycle, or high pulse repetition rate. Mechanical -- Mounting: 19" rack mount with standard chasis slides. RF Connections: Input, type N Female (rear mount), Output, type N female (rear mount), Output sample port, type N Female (front panel mount) BNC type connector. Cooling: Built-in internal cooling (intake and exhaust located in the rear). Electrical: Prime Power: Single phase, 230 Volts plus/minus 10%, 50-60 Hz. Provide at least two year warranty and onsite operation and maintenance training for customer representative at the customer facility. The Amplifier System should include system specifications, operational instructions, schematic block diagrams, replaceable parts lists and theory of operation. The provisions and clauses in the RFQ are those in effect through FAC 97-16. This procurement is a total small business set-aside. The SIC code and the small business size standard for this procurement are 3825 and 500,respectively. The quoter shall state in their quotation their size status for this procurement.
