C-BAND KLYSTRONS
VKC 7988 B2 TROPOSCATTER
COMMUNICATIONS SERIES
The VKC7988 Klystrons Series are designed for use
in cost effective ground communications systems,
which exploit the troposphere scattering effects at
microwave frequencies, including mobile
communication systems.
These four cavities klystrons are CW operation,
tunable in the 4.4 to 5.0 GHz frequency range by
using a tuning mechanism with no requirement for
complex external monitoring equipment.
