Ultrahigh-power amplitude limiter

Abstract

The invention is applicable to the technical field of electronic devices, and provides an ultrahigh-power amplitude limiter, which comprises a first isolation module, a first amplitude limiting module, a second amplitude limiting module and a second isolation module, each amplitude limiting module comprises at least two diode units; the first isolation module is connected with the first end of thefirst amplitude limiting module, the first end of the second amplitude limiting module and the second isolation module. The positive electrode of each diode unit of the first amplitude limiting module is connected with the first end of the first amplitude limiting module, and the negative electrode of each diode unit of the second amplitude limiting module is connected with the first end of the second amplitude limiting module. According to the ultra-high power amplitude limiter, the plurality of diode units are connected in parallel in the first amplitude limiting module, the junction capacitance of the diodes can be reduced, the number of the diodes is increased, the power resistance of the amplitude limiter is improved through the rectification characteristic of the second amplitude limiting module, and the reliability of the ultra-high power amplitude limiter is further improved.

Description

technical field [0001] The invention belongs to the technical field of electronic devices, in particular to an ultra-high power limiter. Background technique [0002] High power microwave (HPM) refers to a source of coherent electromagnetic radiation with an instantaneous peak power exceeding 100 MW and a radiation wavelength ranging from centimeters to millimeters, that is, a frequency between 0.3 GHz and 300 GHz. With the rapid development of high-power microwave weapons and the maturity of electronic countermeasure technology, the electromagnetic environment faced by today's electronic equipment is more complex and the threat it receives is even greater. Due to its high power and high frequency, high-power microwaves have great interference and harm to electronic equipment, and the protection requirements for high-power microwave weapons are becoming more and more urgent. [0003] With the development of electronic technology and the progress of semiconductor technology,...
