Abstract :
This paper is concerned with new and substantial increase in available cw power levels at millimeter-wave frequencies. Average power in excess of five kilowatts has been achieved at 55 GHz in a forward wave amplifier with about 20 db gain. Bandwidths of 1 GHz and efficiencies of greater than 30% have been observed. These results followed from the extension of conventional traveling wave tube design techniques with particular care in the areas of mechanical tolerances and beam control.
