Feasibility Demonstration of a High Power Wideband TWT with Low AM/PM Distortion.
Abstract
Loss-line stabilized tubes have been under development at Litton Industries under the supervision of the Naval Research Laboratories since 1973. Early developmental tubes demonstrated high power, wide bandwidth and efficient operation. In-band distributed loss techniques were developed to form attenuator sections to provide lower bandedge stability and to allow efficient operation at the high frequency bandedge. Stabilization problems, however, at the upper bandedge prevented operation at full design perveance. In the last tube preceding this Contract, upper bandedge stability techniques were improved significantly; but, the tube exhibited in-band regenerative oscillations which prevented direct demonstration of this stability improvement. The two tubes built under this Contract both demonstrated oscillation stability at design perveance and fully demonstrated the potential of loss line stabilized tubes. The design changes and the demonstration of these two tubes as discussed in this report.
