A 70 GHz second-harmonic frequency-doubling gyroklystron with four cavities has been studied. The input cavity operates in the fundamental harmonic TE01 mode at 35 GHz and the other cavities operate in the second harmonic TE02 mode at 70 GHz. The quality factor and mode conversion of the bunching cavities were studied in detail with field matching analysis to reduce the RF crosstalk of the 70 GHz TE01 mode between cavities. And the RF circuit was designed and optimized to enhance operating bandwidth and electron efficiency. And then a 70 GHz second-harmonic frequency-doubling gyroklystron was designed. 256 kW output power, 44 dB saturation gain, 28% electron efficiency with about 160 MHz instantaneous bandwidth were obtained by PIC simulation at 70 kV, 13 A electron beam.
