750W Outdoor EIK Amplifier
for Satellite Communications
K a - B a nd
The VZA-6903E
750 Watt EIK Amplifier
— high efficiency in an
environmentally sealed
compact package
designed for outdoor
Easy to Maintain
Provides up to 750 watts of power in a rugged
and compact weatherproof package, digital ready,
for wideband, single- and multi-carrier satellite
service within the 27.0 – 31.0 GHz frequency
band. Ideal for transportable and fixed earth
station applications.
Modular design and built-in fault diagnostic
capability via remote monitor and control.
Cost Effective and Efficient
Mounting at the antenna improves performance
through minimized cable losses and saves cost in
system design. Employs a high efficiency, integral
cooling system for light weight and compact size.
Global Applications
Meets International Safety Standard EN-60215,
Electromagnetic Compatibility 89/336/EEC and
Harmonic Standard EN-61000-3-2 to satisfy
worldwide requirements.
Worldwide Support
Backed by over three decades of satellite
communications experience, and CPI’s worldwide
24-hour customer support network that includes
fifteen regional factory Service Centers.
Designed and built to survive in extremely
adverse environmental conditions (-40º to +55ºC)
and features increased cooling margin for
longer life.
Simple to Operate
User-friendly microprocessor-controlled logic
with integrated RS422/485 computer interface.
Digital metering, pin diode attenuation and
optional integrated linearizer for improved
intermodulation performance.
