SBIR-STTR Award

The objective of this proposal is to demonstrate the feasibility of producing a lighter, smaller and more efficient solid-state power amplifier for the JTIDS system that is flight qualified for the E2-D Advanced Hawkeye aircraft. Because space and weight is extremely critical aboard the E2-D Hawkeye Aircraft, the present JTIDS power amplifier with its massive size and weight is a prime candidate for a redesign effort. With present day semiconductor technology, a lighter, smaller JTIDS power amplifier design is possible that could possibly save as much or more than half the weight and volume of the present JTIDS high power amplifier, while preserving or enhancing the performance of the power amplifier.

Benefit:
Significant weight and volume savings for RF amplifiers

Growing network centric warfare needs places ever-increasing demands on airborne platforms. Growing payloads of upgraded avionics, radars, and communications assets require that all WRAs subject to redesign for weight and/or volume savings are targets for replacement. Under a Phase II effort, NSS will design, fabricate, test and deliver and working prototype of a 1 Kilowatt JTIDS high-power amplifier. The resulting unit will weigh less than half that of the current HPA. The NSS design will utilize mature LDMOS technology, in a parallel fault-tolerant architecture. The new unit will require no modification to electrical or cooling systems.
