Abstract:
Ku-band (14-14.5 GHz) folded waveguide TWT operated at the beam voltage and current of 6 kV and 0.1 A, respectively, has been studied experimentally. The RF circuit is designed by using a linear theory 1] and its predicted gain for a single stage is 20 dB. The cold test of the assembled RF circuit shows a good agreement with the theoretical prediction 2].
