The phenomenon of passive compression of frequency-modulated (FM) pulses in a dispersive media (DM) was used to increase the peak microwave power up to the multigigawatt level A helically corrugated waveguide was used as the DM, while a relativistic X-band backward-wave oscillator (RBWO) with a descending-during-the-pulse accelerating voltage served as a source of FM pulses Compression of pulses down to a halfwidth of 2 2 ns accompanied by a 4 5-fold power increase up to a value of about 3 2 GW has been demonstrated.
