Abstract :
The recent experimental results of a Ka-band second harmonic gyroklystron amplifier are presented. The peak output power of 212kW at 35GHz has been measured with a 3dB bandwidth of 155MHz. The tube is operated at electron beam voltage and current of 58 kV and 23 A, respectively. The efficiency is approximately 16% and the gain is about 24 dB.
