Abstract
Overall DC-to-RF conversion efficiency continues to be the most significant figure of merit for space TWTs. Improvements in TWTA efficiency immediately translate into potential revenue increases for satellite operators since additional transponders can be 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. Efficiencies >70% are now routine (at least at Ku-band). This paper will discuss the results of several experiments to improve TWT efficiency.
