Solicitation number DAAH01-00-R-RR01 is hereby issued as a request for proposal. Commercial Item -- one (1) 140-1000 MHz High-Power UHF Pulse System with the following minimum specifications and delivery schedule. NOTE: Manufacturer expertise should be incorporated in the final product. If manufacturer experience determines a more efficient or useful method for accomplishing a task than is contained in this scope, please submit any change to the specifications in writing to the Government. The goal is to obtain the most efficient and value-added pulse-amplifier system available in industry with the specified output powers and duty cycles. The Amplifier system will utilize the Burle 4616 V8 and the 94402E Beam Power Tetrode as the final stage RF generating device. The amplifier shall be capable of producing the following parameters at the output of the unit: Frequency Duty Peak Power 140 MHz to 600 MHz .007 325KW 140 MHz to 600 MHz .02 250KW 600 MHz to 799 MHz .01 200 KW 799 MHz to 1000 MHz .01 175 KW The pulse repetition rate shall be continuously adjustable from 1 to 1000 pulses per second. The RF output pulse widths shall be continuously adjustable from 1.0 microseconds to 250 microseconds. The unit shall be capable of supplying essentially rectangular RF pulses whose magnitude is continuously variable from 50 KW -peak power to maximum cavity amplifier output. Pulse to pulse variation in RF power amplitude, shall not exceed .1 dB when triggered by a constant pulse train. The units shall have calibrated controls mounted on the front panels for the purpose of varying the pulse width, repetition rate and frequency from the minimum to maximum limits called for in these specifications. The unit shall be designed to allow the pulse width and repetition rate to be carried from the minimum to maximum without further adjustment to the amplifiers, power supply or modulator. The rise time from the 10-90% level of the RF output pulse shall be no greater that 100 nanoseconds. The fall time of the RF output pulse from the 90-10% level should be less than 200 nanoseconds. The pulse droop shall be less than 10% at any pulse width up to 200 microseconds at the minimum and maximum output power. The unit shall have a high voltage power supply with an output that has a current and voltage capacity at least 25% greater than required for maximum power output at either frequency band. The unit shall incorporate sensing circuitry to detect the following conditions: Average output current in excess of amplifier limits; Any overload or over temperature conditions in the cavity tube or high voltage section; Duty cycle sensing circuits that will power off the high voltage if a duty cycle exceeding the equipment capabilities is selected; Removal of high voltage if cavity arcing occurs. Metering shall be provided on the front panel of the units to indicate the following parameters: Output amplifier filament voltage; Output amplifier filament current; Output amplifier plate voltage; Output amplifier average plate current; Output amplifier control grid current; Output amplifier control grid voltage; Output amplifier bias voltage; Power supply high voltage; Average power supply current; Driver or oscillator high voltage supply voltage; Driver or oscillator high voltage supply current. The unit shall utilize RFI reduction techniques; this shall include doors with control knobs protruding through them and all other filtering or shielding deemed necessary to reduce interference and preclude operating personnel hazards to RF fields. The unit shall be equipped with a complete safety interlock system. This shall include all doors, the pulse high voltage terminals, the time delay relay, the high voltage supply and all other areas that may be hazardous to personnel. The unit shall be capable of radiating at maximum power on any frequency within these specifications, a RF signal whose second harmonic is at least 30 dB below the fundamental frequency. The following parameters should be accessible on the front panel using a RF coaxial connector: Detected RF sample of frequency output pulse. Detected RF sample of driver or oscillators output pulse; A sample of the high power modulator output pulse. Peak pulse current or average current through the high power tubes shall not exceed 20% of the tubes manufacturer ratings. The output for each band shall have a 3 1/8" output connector and a bi-directional coupler for the purpose of monitoring the output power and VSWR. One for each operating band deemed necessary in the design. The unit is also to be furnished with transmission adapters to go from the 3 1/8" lines to a connector that will mate with a RF-220 coaxial line. (One for each band.) Remote configuration and operation shall be provided viaGPIB/IEEE-488 format. The unit shall be designed with ergonomics and ease-of-use in mind. The subassemblies shall be rack mounted and on heavy rollers, whenever feasible, to allow the assemblies to be pulled out of the main frame for ease in maintenance. The equipment shall be capable of operating from 440 VAC, 60 cycles, 3 phase, 230 VAC, 60 cycle, 3 phase, delta and 208 VAC, 60 cycle, 3 phase wye. The unit's chassis and mounts for all components and wire terminal blocks shall be clearly marked with a symbol and number that can be used as a reference on the schematic diagrams of the unit. All front panel controls shall have nomenclature describing their function. The frequency stability of the units shall be .02% or less during operation. The unit shall be equipped with appropriate RF protection devices at all stages. All plumbing for the purpose of removing heat shall be done with PCV and or brass. Manuals -- The unit shall be supplied with booklets, manuals, or specification documents which shall be marked such that the Government may provide the information to third parties to support test and maintenance purposes. The information shall contain: Theory of operation; Operation instructions including GPIB/IEEE-488 commands; Individual subassembly schematic diagrams; Block diagrams showing all interconnecting wiring between subassemblies; Complete schematic diagrams of complete unit; Itemized list of components, their values and manufacturer; All test data requested in these specifications; Separate diagram showing all interlocking circuitry; Manufacturer suggested maintenance and schedules.
