STUDY OF ACTIVE MICROWAVE COMPRESSORS EXCITED BY MAGNICON RADIATION AT A FREQUENCY OF 11.4 GHz

摘要

We present the results of a study of single-channel and two-channel compressors of microwave pulses, operated at a frequency of 11.4 GHz, in which a high-Q factor storing resonator and a novel plasma switch are used. In the single-channel compressor excited by magnicon radiation at a frequency 11.4 GHz, 24-MW pulses have been obtained for a compression ratio equal to 8. In the two-channel compressor, coherent composition of pulses with the use of a 3-dB directional coupler has been demonstrated. Compressed pulses with powers of 9 to 11 MW and durations of 50 to 60 ns have been obtained at the incident-power level 1-1.5 MW, which corresponded to the compression ratio k = 8-9.3.
