Abstract :
We present the results of theoretical analysis and numerical simulation of a two-stage multiple cavity klystron oscillator in W band. Small-signal theory of the oscillator is developed and start-oscillation current and oscillation frequency are calculated. Output power and efficiency is determined from large-signal time-domain particle-in-cell simulation. Oscillators with different number of cavities are compared.
