RCA 1A5V4  
Written by Accutron on 2008-05-10  

The RCA 1A5V4 is a traveling-wave tube of unknown specification. Traveling-wave tubes greatly amplify RF signals by using a high power electron beam which fires down the center of a helical coil, interacting with a parallel RF signal which is simultaneously being carried by the coil itself. This results in a velocity modulation feedback interaction between the RF signal and the electron beam, producing an amplified RF output. Traveling-wave tubes are considered broadband devices, with frequency ranges of up to three octaves.
