Research on S-band High Efficiency Air Cooled Pulse TWT

To meet the requirements of a new electronic countermeasure radar system for higher output power and higher efficiency of
$\mathbf{TWT,}$
an S-band high efficiency air-cooled pulse
$\mathbf{TWT,}$
was developed. This paper introduces the main components of the
$\mathbf{TWT.}$
Through the simulation design of each component and combined with the design of high-power heat dissipation structure, the development of S-band
$\mathbf{TWT}$
sample tube with pulse output power of
$12\mathbf{kW,}$
duty cycle of 10%, total efficiency of 50% and air cooling heat dissipation is realized.
