Traveling Wave Tube Amplifier

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.

Traveling wave tube amplifier.

When test needs call for higher power and higher frequency consider our t series microwave amplifier line 1 to 50 ghz 40 to 20 000 watts cw and pulse. 40 to 20 000 watts. Amplification is done through the prolonged interaction between an electron beam and radio frequency rf field. Travelling wave tubes are broadband microwave devices which have no cavity resonators like klystrons.

Travelling wave tubes are non resonant structures that offer continuous interaction of applied rf field with the electron beam over the entire length of the tube. 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. A travelling wave tube is a high power amplifier used for the amplification of microwave signals up to a wide range. Traveling wave tube amplifiers twta twt amplifiers for high power microwave test applications.

Twit are vacuum tubes used as high gain low noise wide bandwidth microwave wideband amplifiers a twt is capable of gains from 40 to 70 db with bandwidths exceeding two octaves. It is a special type of vacuum tube that offers an operating frequency ranging between 300 mhz to 50 ghz. Twt amplifiers twta traveling wave tube amplifiers. The heated cathode at one end of the tube produces a beam of electrons and is attracted to the collector at the other end of the tube.

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. Travelling wave tube is a cylindrical structure which contains an electron gun from a cathode. A bandwidth of 1 octave is one in which the upper frequency is twice the lower frequency. The traveling wave tube can be used as a medium or high power microwave amplifier.

The twt because of its construction and working principle has enormous bandwidths and low noise. Construction of travelling wave tube. Quarterwave manufactures a complete line of popular traveling wave tube amplifiers. Traveling wave tubes abbr.

The t and tp series. The main attraction of these devices is their very high gain 30 60 db linear characteristics and 1 2 octave bandwidth. 1 to 50 ghz. We have a selective inventory of traveling wave tubes twt and traveling wave tube amplifiers twta available separately or integrated to.

The 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.
