Compact

Provides up to 400 watts of power in a 3 rack 
unit package, digital ready, for wideband, single- 
and multi-carrier satellite service in the Ku-Band 
frequency range. Ideal for transportable and fi xed 
earth station applications where space and prime 
power are at a premium.

Efficient

Employs a high effi ciency dual-depressed 
collector helix traveling wave tube backed by 
many years of fi eld-proven experience in airborne 
and military applications.

Simple to Operate

User-friendly microprocessor-controlled 
logic with integrated computer interface. 
Digital metering, pin diode attenuation and 
optional integrated linearizer for improved 
intermodulation performance.

Global Applications
