摘要：

Test results of high-voltage one- and four-channel radio-frequency (RF) generators based on the coaxial gyromagnetic ferrite-filled nonlinear transmission lines (NLTL) with external magnetic bias and RF-modulation frequency of a high-voltage pulse envelope of similar to 8 GHz are presented. Electrical strength of oil-isolated NLTLs was tested in a compact version of one-channel generator based on the RADAN driver at a repetition rate of 100 pps. In case of a stationary setup, 5-ns pulse with -500 kV amplitude was split into 4 channels with individual NLTLs. Gyromagnetic line output pulses had fast damped RF-modulation with a maximum modulation depth more than 50% and the peak amplitude of -200 kV. Independent control of a delay time in each channel was realized by the coaxial spiral lines with a central biased ferrite core. The coherent summation possibility of RF fields in the free space radiated by a 4-channel system of conical dielectric antennas was demonstrated.
