Abstract

The invention discloses a K-wave-band high-efficiency continuous wave space travelling wave tube. The travelling wave tube comprises a double anode electron gun (1), a slow-wave circuit (2), a periodic permanent magnetic focusing system (6) and a level-four voltage reduction collector (3), wherein the slow-wave circuit (2) is connected to the double anode electron gun (1); the periodic permanent magnetic focusing system (6) is installed on a periphery of the slow-wave circuit (2); and the level-four voltage reduction collector (3) is connected to the slow-wave circuit (2). Two ends of the slow-wave circuit (2) are connected to an input waveguide (4) and an output waveguide (5). By using the K-wave-band high-efficiency continuous wave space travelling wave tube, the structure is designed reasonably, electronic efficiency is high, collector efficiency and total efficiency are high too, and performance is stable.

Description

technical field [0001] The invention relates to a traveling wave tube, in particular to a K-band high-efficiency continuous wave space traveling wave tube with high output efficiency, long service life, good reliability and good nonlinear index. Background technique [0002] The traveling wave tube is a microwave electron tube that realizes the amplification function by modulating the speed of the electron injection. The traveling wave tube is characterized by wide frequency band, high gain, large dynamic range and low noise. Difference / center frequency) can reach more than 100%, the gain is in the range of 25-70 decibels, and the noise figure of the low-noise traveling wave tube can reach as low as 1-2 decibels. Therefore, modern traveling wave tubes have become military radars, military electronic countermeasures, Important microwave electronic devices for relay communication, satellite communication, live TV satellite, navigation, remote sensing, remote control, telemetry...
