Abstract
To increase the frequency without restricting the power and vice versa, of vacuum tubes such as triodes and tetrodes for high-frequency amplification, especially for radio and television broadcasting designers are often limited by the relatively high output capacitance between the anode and the grid of the tube. To reduce this capacitance, especially when the tube is in a circuit for extracting energy from coupled cavities, the cavity coupling is integrated into the tube itself.
