Microwave tubes are electron guns for generating linear beam tubes. A microwave tube generates and amplifies higher frequencies in the microwave range of frequency spectrum. When a microwave tube is energized, the electrons are emitted from the cathode and are focused on the control grid. The emitted electrons are focused by a low positive voltage. To Magnetron imageaccelerate the electron beam, a very high positive DC voltage in equal amplitude is applied at the accelerator and buncher grid. The buncher grids superimpose AC voltage on DC voltage, which generates an electrostatic field between the buncher grids. The direction of the generated electrostatic field is governed by the frequency present in the microwave tube cavity. The continuous change in an electrostatic field accelerates and deaccelerates the electron beam.

Microwave tubes are vacuum electron devices used for the generation and amplification of radio frequencies in the microwave range. An established technology area, the use of tubes remains essential in the field today for high-power applications.
