C-Band Klystrons
VKC2489 - Extended C-Band Series
The Extended C-Band klystron series is designed for use in ground
based earth-to-satellite communication amplifiers. This family of
klystrons provides a minimum output power of 3350 watts over an
instantaneous bandwidth of 45 MHz. These klystrons can be
configured to provide users with 6,12, or 24 channel configurations
thus allowing operators to select preset center frequencies within
seconds. As an option, Digital Fast Tuner System (DFTS) channel
changers are available for sub-second selection of up to 50 channels.
