The compressor contains the oversized cylindrical cavity with two interference output units each in the figure of a circular waveguide H-tee. The H-tees are coupled by a waveguide section and the energy is extracted synchronously through two output ports. The synchronism is provided through using a single microwave switch mutual for both H-tees. Simulation and experimental study of the X-band microwave compressor were carried out. The simulation made it possible to optimize the configuration of the oversized storage cavity and the output element. The amplification factor was 14 dB when the energy was extracted though one output unit at the output pulsewidth of 6...7 ns. Amplification factor and the output power were increased by 2dB and the pulsewidth was decreased down to 3...3.5 ns when the energy was extracted synchronously through two output units.

Results of the experimental investigation of the resonant microwave pulse compression system operating in a 10 cm wavelength region are presented. The system contains two multimode resonators for storing high frequency energy and a waveguide bridge for the fast and synchronous energy extraction. When powered from a magnetron generator having a radiation power of 5 MW and pulse duration of 4 µs, micro wave pulses with an output power of ~0.8 GW, duration of ~5 ns, and pulse repetition rate up to 100 Hz were obtained in this compression system.

“…Active compressors achieve this by accumulating the energy of input pulse for a relatively long period of time and then exhausting the accumulated energy in the form of a short high-power output. Efficient microwave pulse compression is needed in several fields of science and engineering: Compressors are used as components of particle accelerators [1,2] and radars [3], and utilized in data transmission [4], energy transfer [5], plasma heating [6], and biological studies [7].…”

Abstract-Proper design of efficient microwave energy compressors requires precise understanding of the physics pertinent to energy accumulation and exhaust processes in resonant waveguide cavities. In this paper, practically for the first time these highly non-monotonic transient processes are studied in detail using a rigorous time-domain approach. Additionally, influence of the geometrical design and excitation parameters on the compressor's performance is quantified in detail.
