AB  - An integrative high power microwave device is proposed, which consists of a 
      high-efficiency L-band Magnetically Insulated Transmission Line Oscillator (MILO) 
      and a discal TEM-TE11 mode converter. The MILO with a shrunken load composed of a 
      step-like cathode and a ladder-like beam collector can generate a 1.58 GHz, 5.7 
      GW microwave with the efficiency of 20.8% at the diode voltage of 560 kV in 
      simulation. The discal converter utilizes a pair of sectorial two-double radial 
      waveguides and a pair of sectorial cross section waveguides to adjust the 
      phase-difference and realizes the mode conversion in a length of less than half 
      wavelength at 1.58 GHz. In the preliminary experiment, the proposed device 
      generates over 2 GW, 1.575 GHz microwave with the pulse duration of over 50 ns in 
      a 420 kV diode voltage; the corresponding efficiency is 14.9%; the radiation 
      pattern is the ideal TE11 mode.
