The work presented describes the characteristics of single stage and severed high-efficiency, high-power traveling-wave tube amplifiers operating in {ital X} band at 8.76 GHz. Average amplified output powers of 210 MW have been achieved at 24% efficiency. At high output power levels ({gt}100 MW) sidebands develop increasing the average radiated power to over 400 MW with a microwave conversion efficiency of over 45%. In single frequency operation phase stability to within {plus minus}8{degree} has been demonstrated.
