Abstract :
W-band Folded Waveguide (FWG) TWTs with moderately high-power and broad-bandwidth are a key device for many applications, such as radar and imaging systems. This letter presents the development of a 10 GHz bandwidth 100 W W-band FWG pulsed TWT. The test results show that this TWT is capable to offer over 100 W output power with 10.1 GHz bandwidth.
