VZC-6964

      The VZC-6964, 400W compact medium power amplifier, high effi ciency in a compact package, are for Satellite Communications.What in Compact has said, Provides 400 watts of power in a 3 rack unit package, digital ready, for wideband, single- and multicarrier satellite service in the 5.850-6.650 GHz frequency band. Ideal for transportable and fixed earth station applications where space and prime power are at a premium.

      Something about efficient, Employs a high efficiency dual-depressed collector helix traveling wave tube backed by many years of field-proven experience in airborne and military applications.The VZC-6964 is simple to operate. User-friendly microprocessor-controlled logic with integrated computer interface. Digital metering, pin diode attenuation and optional integrated linearizer for improved intermodulation performance. The VZC-6964 's global applications are meeting international safety standard EN-60215, harmonic standard EN-61000-3-2 and electromagnetic compatibility 89/336/EEC to satisfy  worldwide requirements.The VZC-6964 is easy to maintain, for modular design and built-in fault diagnostic which is capability with convenient and clearly visible indicators behind front panel door for easy maintainability in the field.
