Traveling Wave Tube Amplifier Wiki

The twt belongs to a category of linear beam tubes such as the klystron in which the radio wave is amplified by absorbing power from a beam of electrons as it.

Traveling wave tube amplifier wiki. It is a hybrid combination of solid state and vacuum tube electronics which encloses a solid state driver amplifier sspa traveling wave tube amplifier twta and electronic power conditioning epc modules into a single unit. Amplification is done through the prolonged interaction between an electron beam and radio frequency rf field. An rf signal is thus supplied to the section of. Unlike other vacuum tubes such as a klystron or a traveling wave tube twt the magnetron cannot function as an amplifier in order to increase the intensity of an applied microwave signal.

A microwave power module mpm is a microwave device used to amplify radio frequency signals to high power levels. The magnetron serves solely as an oscillator generating a microwave signal from direct current electricity supplied to the vacuum tube. Travelling wave tube is a cylindrical structure which contains an electron gun from a cathode. Construction of travelling wave tube.

Belonging to the traveling wave tube family it is an oscillator with a wide electronic tuning range. A travelling wave tube twt is a specialized vacuum tube that is used in electronics to amplify radio frequency rf signals in the microwave range. Many microwave amplifiers are specially designed valve amplifiers such as the klystron gyrotron traveling wave tube and crossed field amplifier and these microwave valves provide much greater single device power output at microwave frequencies than solid state devices. An electron gun generates an electron beam that interacts with a slow wave.

I propose we merge it back in as a section or two. A backward wave oscillator bwo also called carcinotron a trade name for tubes manufactured by csf now thales or backward wave tube is a vacuum tube that is used to generate microwaves up to the terahertz range. The da consists of a pair of transmission lines with characteristic impedances of z 0 independently connecting the inputs and outputs of several active devices. 2005 when there was a consensus to change title from traveling wave tube amplifier to traveling wave tube engineer bob did that but then also without any prior suggestion or comment took out the twta bits and made a new article that has remained unreferenced and nearly orphan.

Their average output power capability falls between. The twt belongs to a category of linear beam tubes such as the klystron in which the radio wave is amplified by absorbing power from a beam of electrons as it passes down the tube.
