Third-Order Intermodulation Reduction by Harmonic Injection in a TWT Amplifier

  title={Third-Order Intermodulation Reduction by Harmonic Injection in a TWT Amplifier},
  author={Michael Wirth and Aarti Singh and John E. Scharer and John H. Booske},
A method for reducing the two-tone third-order intermodulation products arising from two carrier frequencies at 1.95 and 2.00 GHz is demonstrated in a traveling wave tube-distributed amplifier. The optimum amplitude and phase of an injected second harmonic and the resulting intermodulation suppression of up to 24.2 dB are examined for fundamental drive levels approaching saturation.
