Problems solved by technology

[0003] Traditional vacuum devices generally use hot cathodes, which have the disadvantages of large volume, low work efficiency, slow reaction speed, and easy damage
[0004] Compared with the hot cathode electric vacuum radiation source, the solid-state semiconductor radiation source device has the advantages of small size, integration, and fast response speed, but it has the disadvantages of weak anti-interference, radiation resistance, and low power, especially in the space environment. The reliability of solid-state radiation source devices is difficult to guarantee

Abstract

The present invention relates to a cold cathode compact amplifier. It includes a high-frequency interaction system, an input structure, an output structure, a collector and a cold cathode electron gun; the high-frequency interaction system includes a shell and a periodic slow-wave structure; one end of the shell is sealed with the cold cathode electron gun, and the other end is connected with the collector Extremely sealed connection; the input structure is hermetically connected to the shell in a way of penetrating the shell, and the input structure is arranged on the end of the shell close to the cold cathode electron gun; on the end close to the collector. By using the cold cathode electron gun as the electron source, with the periodic slow-wave structure, the high-frequency field is used to modulate the density of the electron injection. The modulated electron injection enters the high-frequency interaction system and interacts with the high-frequency electromagnetic field, exchanging energy and realizing the signal. Therefore, the number of cycles of the periodic structure is greatly reduced, and the volume of the electric vacuum amplifying device and the processing difficulty of the device are reduced.

Description

technical field [0001] The invention belongs to the technical field of electric vacuum devices in microwave, millimeter wave, submillimeter wave and terahertz frequency bands, and relates to an amplifier, in particular to a cold cathode compact amplifier. Background technique [0002] Microwave, millimeter wave, submillimeter wave, and terahertz electric vacuum devices have been widely valued as indispensable core devices for military electronic systems such as radar, electronic countermeasures, and space communications. [0003] Traditional vacuum devices generally use hot cathodes, which have the disadvantages of large volume, low work efficiency, slow reaction speed, and easy damage. [0004] Compared with the hot cathode electric vacuum radiation source, the solid-state semiconductor radiation source device has the advantages of small size, integration, and fast response speed, but it has the disadvantages of weak anti-interference, radiation resistance, and low power, e...
