“…Энергетический КПД всех этих генераторов находится в интервале 10−60%, однако в этих оценках не учитываются полные энергетические затраты на генерацию, транспортировку электронного пучка, а также на излучение. С учетом всех энергозатрат энергетический КПД конечных источников СВЧ импульсов по сегодняшним оценкам обычно не превышает 10% [11,12], достигая в исключительных случаях 20−30% [13,14]…”

Nonlinear transmission lines with ferrite have been actively developed and studied for about two decades. At the same time, the first works on this topic date back to the middle of the last century. Nonlinear transmission lines with ferrite find their application in various problems of electrophysics, with the greatest application being found in the problems of pulse sharpening, as delay lines and generators of high-power pulses of microwave radiation. The main scientific and technical results of the development of technologies of nonlinear transmission lines with ferrite are presented in chronological order, starting from lines for sharpening the fronts of voltage pulses, ending with multichannel microwave sources based on them.

“…The repetition rate, greater than 1 kHz, and consistency of the RF output make these devices practical for both low and high power RF applications [2], [3] The technological development of fast, high voltage switching with capabilities up to hundreds of kHz [4]- [6] has motivated the development of high repetition rate RF sources with similar capabilities. Traditional microwave sources cannot operate at these high repetition rates because long electron recombination times increase the space charge in the gap, which limits microwave generation in traditional vacuum systems [7]. NLTLs provide a solid state RF source that can operate above 1 kHz with very little variation [3], [8].…”

A Review of Nonlinear Transmission Line System Design

Nonlinear transmission lines (NLTLs) have been increasingly studied to produce high power microwaves (HPM) at higher repetition rates than conventional HPM devices without requiring the same auxiliary systems. The ability to array NLTLs to produce higher power and achieve beam steering provides an additional capability. This review summarizes the various NLTL topologies designed to achieve these design objectives. Specifically, we summarize modeling and experimental studies for three primary topologies: the lumped element NLTL, the split ring resonator, and the traditional transmission line geometry using nonlinear materials. The lumped element NLTL and the traditional transmission line constructed with nonlinear materials lend themselves to higher power applications, while the split ring resonator is better suited for applications involving antennas. We provide a detailed summary of past studies for these topologies and conclude by exploring ongoing work and future opportunities for technological development.

This letter reports on the operation of a repetitively pulsed relativistic klystron amplifier at 200 pps. The electron beam was reproducibly modulated to ≳60%. Using a 5 kA, 500 kV electron beam and a 500 kW magnetron as inputs, we extracted 3.3 kW average power in 80 ns FWHM pulses of 250–300 MW peak power at 1.3 GHz. Limitations that are directly attributable to the repetitive pulsing at these levels have not been observed.
