Traveling Wave Tube Amplifier

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.

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. 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. 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. The traveling wave tube can be used as a medium or high power microwave amplifier.

Traveling wave tube amplifiers twta twt amplifiers for high power microwave test applications. 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. The main attraction of these devices is their very high gain 30 60 db linear characteristics and 1 2 octave bandwidth. 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.

High power traveling wave tube amplifiers twta high voltage power systems and test equipment for microwave tubes. The t and tp series. Construction of travelling wave tube. A travelling wave tube is a high power amplifier used for the amplification of microwave signals up to a wide range.

Twt amplifiers twta traveling wave tube amplifiers. Travelling wave tubes are broadband microwave devices which have no cavity resonators like klystrons. Traveling wave tubes abbr. 40 to 20 000 watts.

Ifi s twta traveling wave tube amplifiers cw continuous waveform twt gridded pulse cw and twt pulse amplifier product lines fill the requirements for all your high frequency high power microwave testing applications ifi designs manufactures and distributes a full line of twt traveling wave tube amplifiers for both the commercial. 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 bandwidth of 1 octave is one in which the upper frequency is twice the lower frequency. Quarterwave manufactures a complete line of popular traveling wave tube amplifiers.

It is a special type of vacuum tube that offers an operating frequency ranging between 300 mhz to 50 ghz. 1 to 50 ghz. 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. Amplification is done through the prolonged interaction between an electron beam and radio frequency rf field.

We have a selective inventory of traveling wave tubes twt and traveling wave tube amplifiers twta available separately or integrated to.
