Large signal studies on octave bandwidth traveling-wave tubes show that significant improvements in tube linearity can be achieved with harmonic injection, in addition to efficiency enhancements and suppression of parasitic harmonic signals. In multisignal operation considerable reduction of the intermodulation distortion can be expected with this scheme. This requires that the injected harmonic signals be optimized in amplitude and phase with respect to the fundamental signals. In practice the… CONTINUE READING
