A compact P-band relativistic backward wave oscillator is investigated using theoretical and simulation method. The coaxial slow wave structure and the coaxial extractor structure are designed to reduce the size and increase the efficiency of the P-band device. Detailed physical interaction pictures of the oscillator are presented. Typical simulation results are that, at the magnetic field of 1.5 T, a P-band microwave with average output power of 1.58 GW is obtained with efficiency about 32%, when the diode voltage and current are 700 kV and 7 kA, respectively. The optimized electromagnetic structure of the device is only f108 mm×856 mm in size.
