Abstract

The invention belongs to the technical field of broadband helix traveling wave tubes, and provides an efficient broadband helix traveling wave tube with inner diameter hopping for the shortcoming of low output power of the existing broadband helix traveling wave tube. The efficient broadband helix traveling wave tube comprises an input helix, an output helix, a clamping rod, a tube casing and a centralized attenuator. The input helix and the output helix are fixed in the tube casing through the clamping rod. The input helix and the output helix are separated through cutting. Both sides are cut, and the centralized attenuator is arranged. The efficient broadband helix traveling wave tube is characterized in that the inner diameter of the output helix is hopping compared with the inner diameter of the input helix, so that the helix traveling wave tube realizes saturation output power point gathering in a work band. According to the broadband helix traveling wave tube provided by the invention, an inner diameter hopping technology is used to effectively solve the problem of saturation output power synchronization in bandwidth; the output power of the broadband helix traveling wave tube is effectively improved; and the output power is high under an equal excitation input condition.

Description

technical field [0001] The invention belongs to the technical field of broadband helical traveling wave tubes, in particular to a high-efficiency broadband helical traveling wave tube with inner diameter jump. Background technique [0002] With the rapid development of society, military electronic equipment is changing with each passing day. The advantages and disadvantages of military electronic equipment directly reflect the strength of the troops' combat capabilities. If there is no series of broadband high-power electronic devices, they will be in an extremely disadvantaged position in electronic countermeasures. The requirements are getting higher and higher, and the development of high-frequency, high-power, and high-efficiency devices is still a key issue to be solved. [0003] Broadband traveling wave tubes refer to traveling wave tubes that cover a wide range of frequency bands. The expansion of broadband brings not only convenience and speed, but also huge economi...
