Abstract :
A theoretical and experimental study of singly corrugated coaxial transmission lines is given here. The properties of the structure as a transmission line are calculated and the effect of the electron beam is taken into account by a field method. Theoretical values of gain and bandwidth are obtained. The results of the experimental study are compared with the theory. An amplifier giving 50-watts output with 20-db gain and 100-Mc bandwidth at a wavelength of 6.5 cm has been obtained. The best power output and efficiency which have been obtained are 125 watts and 7 per cent, respectively.
