Formation of Rectangular Pulses in an Active Microwave Compressor With an Oversized Compact Storage Cavity

Research output: Contribution to journalArticlepeer-review

Abstract

The microwave compressor of a new design forms high-power rectangular pulses of a spatial length exceeding several folds the longitudinal dimension of a storage cavity. Similar to the known compressor with the single-mode circular cavity, the new one has small overall dimensions due to making the cavity as a meander formed by parallel waveguide sections. The input coupler is the input port of the first section, and the output unit is the output port of the last section. Unlike the known compressor, the waveguide elements of the proposed one are oversized. Requirements for the design are determined and characteristics are estimated. Comparing with the analog compressor, the gain of the proposed one is greater by 7 dB. The processes of energy storing and extraction and the characteristics of the X-band compressor were analyzed by computer simulation. The compressor was tested experimentally, and the results were compared with the simulation data. It was shown that the microwave compressor with the oversized compact cavity worked similar to the analog compressor.
