330 _aThis paper presents the experimental results on the generation of subgigawatt radio frequency (RF) pulses using two types of nonlinear transmission lines (NLTLs). In the high-voltage coaxial lines, we used the following: 1) a periodic gas gap structure and 2) uniformly loaded saturated ferrite with axial bias. The concept of the first line is based on the in-phase composition of RF fields produced by currents in the periodic gas gap structure of the inner conductor. The most stable and efficient narrow-band operation of the system with 12 cylindrical gas gaps (200 kV, 18 ns) was realized at an RF of 1 GHz and an RF power of several hundreds of megawatts. The maximum power conversion reached 10%. The second NLTL lacks spatial dispersion. The self-consistent dynamics of the traveling wave is observed by coherent magnetic switching in ferrites with axial bias. The pulsed voltage driver produced 9-ns pulses of voltage between 110 and 290 kV. With the optimum external magnetic field, the efficiency of energy conversion was 10%. The peak power of oscillations produced on a resistive load was 700 MW. An increase in central frequency from 600 MHz to 1.1 GHz with incident pulse amplitude was found.
