Abstract:

The program to build a 100-W cw amplifier at W-band is described. Two tubes were built to prove the design. The demonstrated results are briefly as follows Small signal gain - 15B Small signal bandwidth - 5 Cw power output 100 W min and Efficiency - 15 min. The tube is a rugged ceramic-metal type with a life expectancy of over 5000 hours. A feasibility study was made of a 5 mm amplifier which will eventually deliver 30 W of cw power at 2 min. Extensive work on gun design has resulted in a gun satisfactory for use in the 2 mm tubes to be built during the next phase. Three 5 mm tubes have been fabricated and evaluated for rf performance. Feasibility of the eventual 2 mm design has been established. Author
