Abstract :
A gridded, PPM-focused, X-band, coupled cavity TWT with a midband efficiency of 49% has been successfully developed. This tube, designated the 8741H, provides a minimum output power of 4 kilowatts peak and 1 kilowatt average over a 300 MHz band and operates reliably at a PRF of greater than 200 KHz. The requirements for high efficiency and high PRF operation dictated the selection of the of the design parameters of this liquid-cooled, air-borne TWT. These features are discussed in further detail in this paper.
