Abstract
A C-Band broadband coupled cavity TWT, and an S-Band PPM focused helix TWT will be described along with the experimental results of more than 50% efficiency. The high efficiency is in part achieved with the voltage elevation of the last few cavities of the circuit or the last few turns of the helix. Further efficiency improvement is obtained with a double stage collector in which only the second stage is biased.
