A novel relativistic backward-wave oscillator(RBWO) is introduced with two kinds of slow wave structure separated by a tapered waveguide. It could obtain an output of C-band and X-band microwave simultaneously by means of a single electron beam. A 2.5-D full electro-magnetic numerical simulation is conducted by using Karat code at diode voltage of 1 MV, beam current of 8 kA, and guiding magnetic field of 3 T. A microwave pulse of TEM mode with power of 1.08 GW and an efficiency of 15% is obtained. Output frequencies are 5.42 GHz and 9.58 GHz respectively with an amplitude difference of 2.17 dB.
