【Abstract】 The extended interacted klystron is a high power millimeter wave electric vacuum device, which is widely used in the field of military radar and electronic countermeasures. In this paper, a Ka-band sheet beam interacted klystron working in 2π mode is studied. The three-dimensional electromagnetic simulation software CST is used to simulate the high frequency characteristics and beam-wave interaction of the device. The simulation results show that the extended interacted klystron can produce 51.5 kW output power with a gain of 29.15 dB and a electron efficiency of 42.1% at an operating voltage of 24.5 kV, a beam current of 5 A and a focusing magnetic field of 0.2 Tesla.更多还原
