Means for generating ultra-wideb and radio-frequency emissions with semiconductor field generators

The paper considers the perspective of using powerful semiconductor subnanosecond electrical pulse generators as radiation modulators. We give the data on determining the amplitude-time and spectral radiation parameters of a synchronous active antenna array, the angular divergence of the array radiation. We also estimate the efficiency of converting the electric excitation energy of the antennas into the energy of the directed ultra-wideband radiation in the main directional lobe. Findings of the research show that the effective peak radiation power of the terawatt level is reached at the excitation power of the gigawatt level, and the effective average radiation power of tens of megawatts is achieved with the primary power consumption of modulators of tens of kilowatts.
