Abstract:

Research and development work is described on a traveling-wave power amplifier tube employing transverse-wave interaction between the negative synchronous wave and a circuit wave on a balanced structure. The theoretical advantage in this arrangement is the possibility of high-power amplification with high overall efficiency, due to the lack of longitudinal or transverse velocity modulation in the spent beam. No d-c pumping process is involved, so that such a tube should be free from noise orbit pumping or beam blowup. Theoretical and experimental work on a circuit composed of a twisted, finned, ridged, circular waveguide has shown that an appropriate dispersion curve, as well as adequate interaction impedance, can be obtained at S-band. A completed RF circuit including all necessary transitions and input and output RF windows has exhibited broadband coupling from 3.5 to 4.6 GHz.
