The VTA-6430A Series are a 500W CW Coupled-Cavity Traveling-Wave Tube covering 28.35-31.00 GHz (Ka-Band) with 1 GHz Instantanous bandwidth, Periodic-Permanent-Magnet Focused, WG-28 (compatible with UG-599/U) Waveguide Input, WG-28 (compatible with UG-599/U) Waveguide Output, and Conduction Cooled. This high-efficiency CC TWT is designed for use in satellite communication amplifers. Custom configurations are also available. These variations in the performance and configuration include: cooling method (affects average power level), mechanical conifguration, and electrical and rf connections.
