Vacuum Electronics

Vacuum electronics are devices that control and amplify electrical signals using vacuum-sealed components rather than solid-state materials. They rely on the movement of electrons through space inside a vacuum tube or similar structure, allowing for high-power, high-frequency operations. These devices are essential in applications like radar, satellite communication, and microwave technology, where their distinct ability to handle high voltages and frequencies outperforms modern semiconductor devices in certain situations. Essentially, vacuum electronics harness the behavior of electrons in a vacuum environment to manage electrical signals efficiently at very high power levels.
