C band magnetron with high stabilization is the focus of magnetron research at present. 5.8 GHz magnetron is studied in both simulation and experiment. π mode frequency of the magnetron is 5.863 GHz in the cold cavity simulation. The frequency separation of the magnetron is 44% between the operating frequency and the adjacent frequency when anode vanes are connected with straps alternative anode vanes at both ends. A magnetron’s output frequency of 5.856 GHz and an output power of 1.2 kW are obtained in simulation. The experiment of the injection locked magnetron is studied in this paper, and the results show that the saturated output power is 1.047 kW and the efficiency is 58%. The frequency and phase difference of magnetron are stabilized when the frequency and the phase are locked.
