Abstract:

Research was completed on the development of a broadband traveling-wave amplifier capable of operating over the frequency range 7500 to 11300 mc with a power output of 100 watts cw, and 20 db minimum gain. This tube, the Z-5161, is of metalceramic construction, and is focused by a permanent magnet. The Z-5161 uses a novel multiplehelix structure as the slow-wave circuit. This circuit has not only solved the problem of power handling capability, which limited power output of previous tubes, but also resulted in a shorter, more rugged tube. The properties of this circuit are described in detail, and curves useful for design are presented. The design and construction of the Z-5161 ws. The permanent magnet used for focusing is also described. Test results for several tubes are discussed. These results show that a broadband 100 watt cw X-band travelingwave amplifier is practical, and that some further increase in power level may be possible. Author
