C-BAND KLYSTRONS VA888 TROPOSCATTER COMMUNICATIONS SERIES The VA888 Klystrons Series are designed for use in cost effective ground communications systems which exploit the troposphere scattering effects at microwave frequencies. These light-weight, space-saving klystrons are CW operation and tunable in the 4.4 to 5.0 GHz frequency range. RF and Electrical Characteristics Frequency Range (Channel Centers) Frequency Range Instantaneous Bandwidth (-3 dB) Output Power – minimum Gain – minimum Beam Voltage - maximum Beam Current – maximum Heater Voltage – maximum Heater Current – maximum 4.400 to 5.000 GHz 7 MHz 1200 W 43 dB 7.5 kV 0.520 A (typical: 0.500A) 6.5 V 8.2 A (typical: 7.9 A) Physical Characteristics Dimensions Weight – approximate Operating Orientation Cooling Collector Flow – minimum Body Flow – minimum RF Connectors: Output: Mates with Input: Mates with Focusing See outline drawings (back page) 38 lb (17 kg) Any position Forced Air 855 lb/h (393 kg/h) 90 lb/h (41 kg/h) UG149A/U or equivalent Coaxial Type “N” plug, UG-21D/U or equivalent Integral permanent magnet cpi cpi For complete information klystrons used in satellite communications, please contact your local CPI office, or CPI Canada Inc.
