Plays in the Rain

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 ﬁ xed earth

station applications.

Cost Effective and Efficient

Mounting at the antenna improves performance

through minimized cable losses and saves cost in

system design. Employs a high efﬁ ciency, integral

cooling system for light weight and compact size.

Reliable

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.

Easy to Maintain

Modular design and built-in fault diagnostic

capability via remote monitor and control.

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.
