A traveling wave tube (TWT) is an electron device used for radio-frequency amplification at microwave frequencies (above 500 MHz) and is the primary means of signal amplification utilized in communication satellites. TWTs are also used for ground broadcast stations, guidance systems and military aircraft radar. TWTs convert DC power to radio-frequency power by synchronizing the radio-frequency wave with an electron beam traveling in a vacuum.

If you listen to XM satellite radio, pay for gasoline with a credit card, watch DIRECTV (R) satellite television programming, make long-distance telephone calls, or watch TV broadcasts from other parts of the world (e.g., live sports events or news), our TWT products helped make that possible!
