摘要：

Saturated instantaneous bandwidth (FWHM) of at least 10% is demonstrated in a Ka-band gyrotron traveling-wave tube (gyro-TWT) with uniform interaction waveguide and magnetic field. A relatively low α (≡ v1 /v11) beam has resulted in stable saturated operation and broad bandwidth. This, together with the overall performance of the tube (18.4-kW maximum power at 18.6% efficiency and 18-dB gain) strongly reinforces the possibility of developing a new generation of millimeter traveling-wave amplifiers based on the gyro-TWT. © 1990 IEEE
