The VZU6997AB-L
Ext Ku-Band
750 Watt TWT High
Power Amplifier—
high efficiency in a
compact package
Global Applications
Provides 290 watts of linear power in a 5 rack
unit package, digital ready, for wideband, singleand multi-carrier satellite service in the 12.7514.50 GHz frequency band. Ideal for transportable
and fixed earth station applications where space
and prime power are at a premium.
Meets International Safety Standard EN-60215,
Electromagnetic Compatibility 2004/108/EC
and Harmonic Standard EN-61000-3-2 to satisfy
worldwide requirements.
Employs a SuperLinear TWT. This HPA
consumes about half the power of competing
SSPAs, and is significantly more efficient than
traditional dual-collector TWTAs.
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.
Easy to Maintain
Modular design and built-in fault diagnostic
capability with convenient and clearly visible
indicators for easy maintainability in the field.
Worldwide Support
Backed by over three decades of satellite
communications experience, and CPI’s worldwide
24-hour customer support network that includes
twenty regional factory service centers.
