C-Band Klystrons
VA936/VKC7936 Series
The VA936/VKC7936 Series of klystron is designed for use in ground
based earth-to-satellite communication amplifiers. The
VA936/VKC7936 Series is available in various configurations and
frequency ranges to suit customer's exact requirements. This family
of klystrons has output power specifications ranging from 1500 to
3350 watts over 40 or 45 MHz of instantaneous bandwidth. 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
(DFTS Model Shown)
of up to 50 channels.
