Abstract

The invention provides a broadband high-power protection module and device based on a tapered transmission line, the whole broadband high-power protection module is of a symmetrical structure, the broadband high-power protection module comprises a dielectric substrate, a grounding metal floor is arranged on the dielectric substrate, and a signal input end and a signal output end are arranged on the dielectric substrate. An input end impedance transmission line, a first gradient transmission line, a first-stage parallel diode array, an intermediate transmission line, a second-stage parallel diode array, a second gradient transmission line and an output end impedance transmission line are sequentially connected between a signal input end and a signal output end in the signal transmission direction. The line width of the first tapered transmission line is gradually broadened in the signal transmission direction, and the line width of the second tapered transmission line is gradually shrunk in the signal transmission direction. The gradient transmission line structure is utilized, the transmission line impedance at the installation position of each level of parallel diode array is reduced, the influence caused by the PIN diode capacitance effect is reduced, and the tolerance power of the protection module is improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic protection, in particular to a broadband high-power protection module and device based on a gradient transmission line. Background technique [0002] With the development of electromagnetic pulse source technology, ultra-broadband radiation sources and high-power radiation sources gradually appear in the public eye. Ultra-bandwidth radiation sources and high-power radiation sources have high radiation power, and the instantaneous peak radiation power exceeds 100 MW, which seriously threatens the security of information systems under strong electromagnetic radiation. As the main port for transmitting and receiving electromagnetic waves, the antenna is an important channel for strong electromagnetic energy coupling. The influx of electromagnetic wave energy from the antenna will bring fatal threats to sensitive devices such as low-noise amplifiers and mixers at the rear of the antenna. The ...
