A continuous wave backward wave oscillator is studied in this paper. The design of the slowing wave system is completed through theoretical calculation and numerical simulation, and the slowing wave system is manufactured through precision machining. In order to improve the output power of the electron tube, a high resistance diode electron gun is used to produce a sheet electron beam with high emission current density. The test shows that the developed BWO can work in the frequency range of 250 ~ 310 GHz, and the output power is 20 mW to 42 mW.
