The invention, which belongs to the technical field of the
plasma amplitude
limiter, discloses a high-power ultra-
wideband plasma amplitude
limiter comprising an input window, a
discharge gap, an output window and an amplitude limiting module. The
plasma amplitude
limiter is reliable in structure, ultra-wide in band and high in
power capacity, is located at the front end of a
receiver, and plays a role in protecting high-power
microwave attacks. The plasma amplitude limiter disclosed by the invention can bear high-power
microwave attack with the highest power magnitude of 10kW in the widest
frequency band range of 10GHz, and a receiving access can be quickly switched off within 10ns, so that the aim of protecting the whole communication
system is fulfilled; a coaxial ultra-
wideband design technology is adopted, a full-hard
welding structure is adopted, the structure is stable and reliable, and the
frequency band range of the plasma amplitude limiter tube covers L, S, C, X and Ku wave bands; the multi-stage pointed-cone-shaped
discharge gaps are adopted,
leakage power is reduced stage by stage, and therefore safe work of the amplitude limiting
chip is guaranteed, and finally the plasma amplitude limiter with high bearing power and short
response time is achieved.
