D BS- Band
The VZU-6995VX
DBS-Band
500 Watt TWT Medium
Power Amplifier
— high efficiency in an
environmentally sealed
compact package
designed for outdoor
operation
Easy to Maintain
Provides 500 watts of power in a rugged and
compact weatherproof package, digital ready,
for wideband, single- and multi-carrier satellite
service in the 17.3-18.4 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, dualdepressed collector helix traveling wave tube,
reducing operating costs.
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.
Reliable
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.
Digital metering, pin diode attenuation and
optional integrated linearizer for improved
intermodulation performance.
