A study effort was conducted to determine the current state-of-the- art in one kilowatt UHF power amplifiers. Studies and investigations culminated in a final technical report containing a detail performance specification and recommended overall design approach for a solid state one kilowatt amplifier. A discussion section is provided which explains the rationale behind the recommended requirements of the detail specification. Investigations included research into the characteristics of UHF airborne transmitters, either in existence or under development, which would be used as drivers for a power amplifier. Specific hardware investigations were conducted in the areas of RF power transistors, power combiners and splitters, and certain keying and control circuits. The results of these investigations were used to develop RF block diagram characteristics of a kilowatt power amplifier. Additional paper studies and analyses investigated cooling requirements, primary power requirements, reliability, packaging and physical characteristics, performance advantages of a reduced bandwidth design, and a comparison of solid state and tube-type kilowatt amplifier characteristics.
