  • Abstract
    In this paper, both second harmonic and third order inter-modulation signals are experimentally injected into a traveling wave tube (TWT) to carry out the research on the suppression of IM3 in a X-band TWT. The results shows that with proper phase and amplitude of injected 2f2 and 2f2 - f1, a significant reduction in the upper IM3 (2f2 - f1) is observed. IM3 suppression of up to 30.67 dB is examined with 2f2 injection when Df = f1- f2 = 5MHz, and 15.75 dB IM3 suppression is obtained with IM3 (2f2 - f1) injection.
