A method of microwave pulse compression was proved experimentally tens of years ago and now it is used in pulse microwave sources for power amplification. The method make resonant microwave energy stored in a high Q-value cavity with following fast energy dumping. The output power value is limited by electric strength of the switch gap and the design of the device. Studies in this report are meant to overcome the limitation. The device contains cylindrical cavity with two output ports and the common output line. The single switch is located in the middle of the cavity relatively to its length so the energy of four cavity sections is dumped through the ports synchronously into the combining output line. The cavity is the oversized cylindrical section bounded by the end caps having the two input ports in order to provide the symmetry of the excited field pattern. Calculation showed the electric field strength in the switch is about 135 kV/cm and the total output power is in the range 0,55-1,0 GW depending on parameters of the cavities. Experimental tests were run in S-band with 5 MW input power pulses. The measured output pulse power was ~ 0,8 GW at pulse repetition rate 10 Hz, output pulsewidth 5,1 ns at -3 dB level and gas pressure in the switch up to 1 bar.
