Improved Efficiency Broadband Amplifiers

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 mobilecommunication 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 bothapproaches.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 systembuilding block, which will facilitate a smooth and confident transition to Phase II. Broadband communications.
