66 -- 1000 WATT RF POWER AMPLIFIER SOL NCI-RFQ-80114-NE POC David Keefer, Contracting Officer, (301)496-8628; William Taylor, Contract Specialist, (301) 496-8628 This is a combined synopsis/solicitation for commercial items, prepared in accordance with the format in FAR 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation and a separate written solicitation will not be issued. This solicitation, No. NCI-RFQ-80114-NE will include all applicable provisions and clauses in effect through FAR FAC 97-04. The acquisition is being made in accordance with the test program for using simplified procedures for certain commercial items authorized in FAR 13.6. The solicitation is set-aside for small businesses. The Standard Industrial Classification Code is 3826 and the business size standard is 500 employees. Background: The Radiation Biology Branch, National Cancer Institute, is developing a Radiofrequency (RF) pulsed Electron Paramagnetic Resonance Spectrometer/imager in order to perform non-invasive physiologic imaging of tissues of intact biologic objects. Current studies have provided the proof of principle in animal models. The next step is to scale the studies up to perform similar experiments on larger objects in the scale, at least, of the human head. Since the requirements of RF power increase significantly with object size, the input RF pulse power to the object must be amplified to at least 1000 watts. This is important in the detection and imaging of free radicals and physiology in larger objects. The pulse widths in EPR experiments are in 10-50 nanoseconds to achieve the desired spectral bandwidth (20-100 MHz). Unlike in NMR experiments, the spectral range of EPR experiments is higher. The frequency range of the EPR imaging experiments is in the range of 100 MHz to 1000 MHz in a single band operation. Therefore, an instantaneous frequency response of the amplification in this frequency range is required. Furthermore, the amplification of the input signal must be distortion (harmonic) free and be biased in the linear range of the amplifier in order for the experiment to be free of artifacts associated with pulse amplification. In addition, the pulses have to be amplified to the desired level with rise times in the order a nanosecond. Since the pulse widths are in 10 ns range, rise times in the order of 1 ns are required. Similar requirements in the fall times are desired as well to ensure the amplification of square wave form. Requirement: The National Cancer Institute is soliciting quotations for pulse power amplifier equipment to meet the foregoing program need. The equipment must meet the following specific requirements: 1) Maximum output power: 1000 Watts 2) Frequency Response: 100 MHz to 1000 MHz; single band operation. 3) Class of operation: Class A bias condition 4) Input and output impedance: 50 Ohms 5) Modulation: 100% in pulse, AM and FM 6) Control: Front panel and remote 7) Monitoring: Forward and reflected power 8) Gain Control: To be provided in front panel 9) Maximum input: 0 dBm 10) Cooling: Forced air cooling required 11) Rise Time/FallTime: 1 -2 nanoseconds 12) Annunciation: Continuous monitoring and identification of fault circuits or modules. The equipment shall have a minimum warranty period of one (1) year, including parts and labor. Delivery shall be made F.O.B Destination, inside delivery, no later than 90 days after receipt of order Offerors must provide descriptive literature, warranties, and/or other materials that demonstrate that their offer meets the foregoing requirements. The contract will be awarded to the responsible offeror with the lowest-price offer that fully meets the requirements of the solicitation. This solicitation incorporates the provisions at FAR 52.212-1, INSTRUCTIONS TO OFFERORS-COMMERCIAL ITEMS, and at FAR 52.212-3, OFFEROR REPRESENTATIONS AND CERTIFICATIONS -- COMMERCIAL ITEMS.
