It is one of the important microwave tubes mainly used for wide bandwidth, high gain, low noise and moderate peak and average power requirement. The TWTs are of two types viz. helix TWT and coupled cavity TWT. The function of modules such as electron gun, magnet, collector is same as used in klystron described below.

WebThe essential features of a typical travelling wave tube Introduction In the past few years, several (radio) amateurs have employed travelling wave tubes (TWTS), colloquially known as 'twits', as microwave power amplifiers. The main attraction of these devices is their very high gain (30-60 dB), linear characteristics and 1-2 octave bandwidth.

WebThen, with the encouragement and support of Eugene (Joe) Dutkowski of the Crane Division of the Naval Surface Warfare Center, I developed an 8-day course on traveling wave tubes that led to the publication in 1994 of Principles of Traveling Wave Tubes. A traveling-wave tube (TWT, pronounced "twit" ) or traveling-wave tube amplifier (TWTA, pronounced "tweeta") is a specialized vacuum tube that is used in electronics to amplify radio frequency (RF) signals in the microwave range. The TWT belongs to a category of "linear beam" tubes, such as the klystron, in which the … See more A Basic TWT The TWT is an elongated vacuum tube with an electron gun (a heated cathode that emits electrons) at one end. A voltage applied across the cathode and anode accelerates the … See more A TWT integrated with a regulated power supply and protection circuits is referred to as a traveling-wave-tube amplifier (abbreviated TWTA and often pronounced "TWEET-uh").
