VZC-6964VM - Communications & Power Industries

400W Outdoor TWT Power Amplifier
for Troposcatter Applications
Tropo C - Band
The VZC-6964VM
Easy to Maintain
Provides 400 watts of power in a rugged and
compact weatherproof package, digital ready,
for troposcatter communications in the
4.4 to 5.0 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 highly reliable helix
traveling wave tube.
Designed and built to survive in adverse
environmental conditions. Operating temperature
of up to 50°C, including solar loading.
Global Applications
Meets International Safety Standard EN-60215,
Electromagnetic Compatibility 2004/108/EC
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.
Simple to Operate
User-friendly microprocessor-controlled logic
with integrated RS422/485 computer interface.
Digital metering and pin diode attenuation for
improved intermodulation performance.
