| Abstract: | Thermal and structural analysis of the coaxial coupler for Ku-band 140 W helix space TWT have been carried out using ANSYS software v.10.1 and discussed in the present paper. To evaluate thermal and structural aspects of the coaxial coupler and helix assembly with three APBN support rods, related studies of the coupler assembly with ten turn of helix and output wave guide coupler for the Ku-band 140 W space TWT during extreme case of operation, i.e. at saturation and with perfectly rigid base-plate at 80°C have also been carried out. |
