Microwave Communication Oscillators of a klystron tube are maintained By circulating bunches of electrons within the cavities. By feedback between the accelerating grid and the repeller By plate-to-cathode feedback By bunches of electrons passing the cavity grids By circulating bunches of electrons within the cavities.

Microwave Communication The cavity resonator Has a low Q factor for narrow operation. Is equivalent to an LC resonant circuit In a reflect klystron has its output taken from the reflector plate Produces a frequency which is independent of the cavity size.
