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.
