Abstract :
A Ku-band high-power lowpass filter with spurious passband suppression up to 40 GHz is proposed in rectangular waveguide technology. The new design consists of a conventional E-plane corrugated lowpass filter cascaded with a quasi-periodic structure tuned to reject the undesired spurious passbands. This new design technique allows the minimum gap of the original corrugated filter to be kept wide enough to permit high-power operation
