A multi-frequency splitter terahertz traveling wave tube frequency doubling device

Abstract

The invention discloses a multi-frequency shunt terahertz travelling wave tube frequency doubling device and belongs to the field of a vacuum electron device. The multi-frequency shunt terahertz travelling wave tube frequency doubling device comprises a sealing tube shell in a vacuum state. The sealing tube shell comprises an electronic gun, a slow wave structure, a focusing system, a high-frequency input or output system, a collector and a concentrated attenuator, wherein the slow wave structure aims at improving harmonic wave information to regulate design, and the design is regulated according to steps. The output system achieves shunt output of fundamental waves and the harmonic waves, the fundamental waves are matched to be absorbed, and the harmonic waves are practical application information. Harmonic wave information in travelling wave tubes is fully utilized, and the frequency doubling amplification is achieved through using modulating nonlinearity to an electronic beam by electromagnetic waves in the device.
