Transparent traveling wave tubes with electron-beam modulation at the cathode
Yu. A. Kalinin, A. S. Fokin, A. V. Starodubov Saratov State University
Abstract:
We consider the results of an experimental investigation of a laboratory prototype of a microwave amplifier based on a transparent traveling wave tube (TWT) with the input signal applied either to a beam-modulating near-cathode grid or (traditional scheme) to the input helix of a slow-wave system. Dependences of the amplifier gain and efficiency on the input-power level are presented. In the TWT scheme with a modulating grid, the electron efficiency reaches 50–56% at a gain of 12–13 dB.
