Abstract

The invention provides a double frequency induction output pipe. The double frequency induction output pipe comprises an input system, a double frequency output chamber and an electron collector; the input system comprises an input chamber and is used for performing density modulation on electron beams through outside input microwaves; the resonant frequency of the double frequency output chamber is n times of the working efficiency of the input chamber; the energy exchange of the electron beams is produced in the double frequency output chamber after the density modulation and the produced high frequency energy is output to the outside; the electron collector is used for collecting remaining electrons after the energy exchange. According to the double frequency induction output pipe, the resonant frequency of the double frequency output chamber is n times of the working efficiency of the input chamber and accordingly the frequency selection is achieved through the selection of the resonant frequency of the double frequency output chamber and high frequency bands of high frequency microwaves can be obtained when low frequency bands of microwave signals are input.

Description

technical field [0001] The invention relates to the field of electric vacuum technology, in particular to a frequency doubling induction output tube. Background technique [0002] The inductive output cavity IOT (Inductive Output Tube), also known as klystrode, is a density-modulated microwave tube that combines microwave triode, tetrode and klystrode. It is a compact Low frequency high power microwave amplifier. In the induction output cavity, the input resonant cavity generates a high-frequency electric field between the grid and the cathode, controls the electron emission of the hot cathode, and obtains a density-modulated electron beam. After being accelerated by the high voltage applied between the grid and the anode, the density-modulated electron beam enters the output resonant cavity after passing through a drift space, and induces a high-frequency voltage on the gap between the output resonant cavity; the density-modulated electron beam and the high-frequency outpu...
