VTA-6430A1 Datasheet, PDF (1/2 Pages) Communications & Power Industries, Inc. – Millimeter Wave Coupled Cavity TWT

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 avail-
able. These variations in the perfor-
mance and configuration include:
cooling method (affects average power
level), mechanical conifguration, and
electrical and rf connections.
