| 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 of up to 50 channels.
