K a - B a nd
The VZA-6906C5
400/500 Watt High
Power Amplifier
— high efficiency in an
environmentally sealed
compact package
designed for outdoor
Easy to Maintain
Provides 400 or 500 watts of power, depending
on configuration, in a rugged and compact
weatherproof package. Digital ready, ideal
for wideband, single- and multi-carrier
satellite service within the 28.35 - 31.00 GHz
frequency band.
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 Millitron coupled cavity 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
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.
