摘要：

Overall dc-to-rf conversion efficiency continues to be the single most significant figure of merit for commercial space traveling wave tube amplifiers (TWTAs). Improvements in TWTA efficiency immediately translate into potential revenue increases for satellite operators, since additional transponders can he carried on board the spacecraft for the same prime power and waste heat handling capacity. The revenue implications of increased efficiency have spurred TWT manufacturers to continue wringing out every possible increase in efficiency. By optimizing both rf circuit and collector designs, overall efficiencies >70% have now become routine. This paper will discuss the results of several experiments to improve TWT efficiency demonstrating how these impressive efficiencies may be achieved.
