A new idea about radial reflex klystron oscillator with a virtual cathode is brought forward to improve microwave power and efficiency. The radial reflex klystron oscillator is combined with a virtual cathode oscillator in one foldaway coaxial diode. The frequency of the virtual cathode oscillator is locked by the radial reflex klystron oscillator and the bunching of the reflex electron beam reflected by the virtual cathode is enhanced. A new type of radial reflex klystron oscillator with a virtual cathode is designed and simulated by 2.5 D PIC. The results of the simulation are presented. 2.5 GW output power is generated with 620 kV voltage, 25 kA beam current and the frequency is 1.25 GHz.
