%X Theoretical research and optimization design of 8mm second harmonic gyroklytron amplifier were reported.A three-cavity,second harmonic gyroklystron amplifier prototype was fabricated according to the results of numerical simulation.Initial experiments show a peak output power of 180 kW at 35 GHz with an efficiency of 13% and a gain of 21dB.A peak output power of 150 kW with a 3-dB bandwidth of 110 MHz(0.3%) at 58kV beam voltage and 25A beam current was obtained.
