PURPOSE: A low voltage driven high frequency oscillation tube is provided which can control the power fed back to an input cavity from an output cavity. CONSTITUTION: According to low voltage driven high frequency oscillation tube, a penetration hole(91) connected to an output cavity(140) is formed on both sides of an anode(90) constructing a top part of the output cavity. A first nut(85) supported rotatably by a circular bracket(80) is connected to the outer circumference of a bolt(95) inserted to be elevated from the inside of the penetration hole. And, a male screw(71) is formed on a front part of a feedback plug(70) installed vertically on the center part of the output cavity and the input cavity, and a second nut(75) is connected to the outer circumference of the male screw. Thus, the fine control of a resonant frequency is enabled by varying the capacity of the output cavity according to the elevation of the bolt.
