VZU-6997AD

Ku-Band
750 W Compact High Power Amplifier
Compact
Provides 750 watts of power in a 5 rack unit package,
digital ready, for wideband, single- and multi-carrier satellite
service in the 13.75-14.50 GHz frequency band. Ideal for
transportable and fixed earth station applications where
space and prime power are at a premium.
Efficient
Employs a high effi ciency dual-depressed collector helix
traveling wave tube backed by many years of field-proven
experience in airborne and military applications.
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.
Global Applications
Meets International Safety Standard EN-60215,
Electromagnetic Compatibility 2004/108/EC and Harmonic
Standard EN-61000-3-2 to satisfy worldwide requirements.
Easy to Maintain
Modular design and built-in fault diagnostic capability
with convenient and clearly visible indicators for easy
maintainability in the field.
