Abstract : This effort was to investigate characteristics of certain high power, high frequency tubes capable of at least 100KW peak output power at up to 32 MHz which contribute to the generation of individual spurious lines in the spectrum in excess of 90 db below the maximum output power. The objective was to identify noise sources within the tubes and recommend design changes to reduce the spurious outputs to the desired levels. The program resulted in a thorough noise generation evaluation of the particular class of tubes, recommended design changes to further reduce the noise generation and noted significant factors that should enable equipment designers to minimize the noise outputs of existing tubes.
