Requirement Description for Custom VLF Transmitter System Solicitation # FA9453-15-R-0079

1. System Description:

The system consists of an amplifier element and a custom controller, which may form a single integrated unit, and may require an output transformer to feed a balanced load. Minimum performance criteria:

Amplifier:

· continuous output power 50 - 70 kW (125 kVA) (prefer high end, may be multiple amps combined)

· Pulse output power 90-110 kW (125 kVA) 50% duty cycle waveform for >=15 minutes (one shot every few hours is adequate)

· 3 dB freq range: 14 - 35 kHz

· total harmonic distortion: < 5 % (3rd and 5th harmonic less than -40 dB of maximum output; all other harmonics at less than -50 dB)

· efficiency at full power >=80% at full power for resistive loads

· no external cooling or ducting

· operate with room temperature up to 50 degrees C

· front panel meters for output voltage and current

· power input: 480 V, 3-phase, 60 Hz

· stair step modulation Controller:

· Sine wave synthesis, 14 – 35 kHz

· Continuous wave and programmable on-off keying

· Independently-specified on-off periods

· 0.5s – 5s duration for each state

· Manual Power control

Transformer:

A custom output transformer with taps may be required, depending on the design, to transmit amplifier power to the load. The intended load is estimated as ~ (25 ( 95) + j0 ( (depending on frequency).

2. Additional Information Responsive offerors shall address the system requirements in section 1 and propose to the following delivery constraints:

Quantity: 1 complete system Delivery: For proposal costing, offerors should assume the following delivery address:

Commander Attn: Greg Devogle

Business Development Office/G5 Building 100

WSMR, NM 88002

The Government will conduct a pre-ship inspection and review at the contractor’s facility prior to delivery. This review shall include testing of the system and training on the system’s operation for Government personnel. Contractor to provide all personnel and equipment necessary to perform the testing and training at the contractor’s facility. The Government will accept or reject system at contractor’s facility.

Delivery timeframe: 6 - 12 months after contract award. Delivery should be made in shipping crates that are also suitable for long-term indoor storage.

OPTIONAL CLINS:

1. CLIN 0003: Proposals should include information and price for offeror-provided on-site support for installation and test at or about time of delivery to Government site.

The contractor shall provide personnel at the installation site at White Sands Missile Range, NM, as needed to perform or support the following tasks:

· No more than one (1) work week

· Unpacking of the VLF transmitter equipment (hereafter referred to as “the equipment”) from the shipping containers in which it is delivered

· Setup of the equipment

· Connection of the equipment to on-site power source and to a suitable antenna or dummy load. This task includes the connection of the equipment to any transformer provided as part of the equipment, or to a tuner provided by the Government, as needed to interface with the antenna or dummy load

· Energization and functional test of the equipment. (This task is similar to or the same as the pre-shipment functional test performed at the contractor’s facility)

· Demonstration of principles of operation of the equipment (This task is similar to or the same as the pre-shipment training performed at the contractor’s facility)

· Any required troubleshooting in the event of performance not meeting specifications

2. Optional CLIN 0004 is for Repair/Overhaul of delivered system and equipment. CLIN 0004 is unpriced at time of award. If Repair/Overhaul services are required, Contracting Officer shall provide in writing a request for service to the Contractor.
