The VZA-6906C6
500 Watt High
Power Amplifier
— high efficiency in an
environmentally sealed
compact package
designed for outdoor
Easy to Maintain
Provides up to 2000 MHz of bandwidth at
500 watts of power in a rugged and compact
weatherproof package, digital ready, for
wideband, single- and multi-carrier satellite
service within the 27.5 - 30.0 GHz or 30.0 to
31.0 GHz frequency bands. Ideal for transportable
and fixed earth station applications.
Modular design and built-in fault diagnostic
capability via remote monitor and control.
Global Applications
Meets International Safety Standard EN-60215,
Electromagnetic Compatibility 2004/108/EC
and Harmonic Standard EN-61000-3-2 to satisfy
worldwide requirements.
Cost Effective and Efficient
Mounting at the antenna improves performance
through minimized cable losses and saves cost in
system design. Employs a high efficiency, dualdepressed collector Millitron coupled cavity tube,
reducing operating costs.
Worldwide Support
Backed by over three decades of satellite
communications experience, and CPI’s worldwide
24-hour customer support network that includes
sixteen regional factory Service Centers.
Designed and built to survive in extremely
adverse environmental conditions and features
increased cooling margin for longer life.
Simple to Operate
User-friendly microprocessor-controlled logic
with integrated RS422/485 computer interface.
Ethernet interface is available as an option.
Digital metering, pin diode attenuation and
optional integrated linearizer for improved
intermodulation performance.
