A radio-frequency amplifier includes at least two double-ended electron discharge devices in coaxial-type, radio-frequency cavity-resonator circuits. Each discharge device has a discharge region so that the amplifier comprises a plurality of longitudinally spaced-apart, electrically connected discharge regions. Each of the discharge regions has a cathode with an anode circumscribing the cathode. At least one grid electrode is disposed between the cathode and the anode. A coaxial input transmission line is loop-coupled to an input cavity-resonator circuit and a coaxial output transmission line is loop-coupled to an output cavity-resonator circuit.
