SBIR-STTR Award

Transistor Power Technology, Inc. (TPTI) is proposing a program to develop a cost effective, solid state, linear, 200 watt amplifier, with an instantaneous bandwidth of 200 to 3000 MHz.The proposed amplifier is designed to serve in a military mobile communication environment driven by multi mode transmitters that operate to complex spread spectrum modulation requirements. The broadband capability combined with an efficient design will simplify mobile system logistics. TPTI’s proposed low risk solution was structured to maximize the technical milestones in accordance with the allocated schedule. We are confident of achieving the proposed goals because of the vast experience of our technical personnel on similar programs. TPTI is proposing to investigate two parallel approaches that will insure the successful accomplishment of this program. The first uses one gain block. The second multiplexes two gain blocks. Simulated analysis is provided to show feasibility of both approaches. During the first six months of Phase I of this program, TPTI will perform simulation and trade-off analysis and verify performance of the proposed building blocks. TPTI is also proposing, under the option period, to integrate and test a quarter system building block, which will facilitate a smooth and confident transition to Phase II.

The overall objective is to develop a cost effective, solid state, linear, 200-watt amplifier, with an instantaneous bandwidth of 200 to 2500 MHz, designed to serve in a military mobile communication environment. The amplifier will be driven by multi mode, complex modulation exciters. The broadband capability combined with an efficient design will simplify mobile system logistics. An overall amplifier efficiency greater than 30% [present broadband systems achieve an overall typical efficiency of only 10%] and size compatible with typical military mobile systems represents the state of the art technology that is now the goal of all military organizations. This is evident from the existing Joint Tactical Communication programs. During Phase I, TPTI has developed small, highly efficient, class AB power amplifier stages and broadband power combining apparatus that significantly reduce the size and cost of the proposed broadband amplifier system. The goal for TPTI is to engineer and integrate the modules, through the Phase II program, and provide an affordable, field worthy product to the US military. Additional testing of the amplifier, in military platforms is proposed to commence during the option program.
