A filter helix consisting of periodic pitch discontinuities can be implemented in the transmission line of a traveling wave tube (TWT) to act as a stopband filter for the second harmonic. This contribution investigates the possibility of integrating such filters in tube regions with tapered helix pitch. Simulation of an L-band TWT predicts increased output power for optimized filter design.
