Model S5CI Series 125
and 225 Watt C-band
Solid State Power
and Compact With CPI
Brick Inside.
Global Applications
With CPI-built RF brick inside and plenty
of thermal margin, SSPA is rock-solid, highly
efficient and easy to maintain. Provides up
to 125 or 225 watts of power in a 5.25"
rack-mountable unit covering the
5.850 - 6.425 GHz frequency band.
Meets International Safety Standards
EN-60950 and EN-60215, Electromagnetic
Compatibility 2004/108/EC and Harmonic
Standard EN-61000-3-2 to satisfy worldwide
Worldwide Support
Multi-Carrier Digital Operation
Highly linear: excellent AM/PM, phase noise
and spectral regrowth performance.
Simple to Operate
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.
User-friendly microprocessor-controlled logic
with integrated RS422/485 computer interface,
digitally controlled attenuator, and optional
Ethernet interface.
