Provides 2250 or 2500 watts of equivalent linear power (1000 or 1110 watts operating) in a compact nine rack-unit package, digital ready, for wideband, single- and multi-carrier satellite service in the 7.9 - 8.4 GHz frequency band. Designed to operate at up to 1260 watts flange linear power for multi-carrier uplinks. Ideal for transportable and fixed earth station applications where space and prime power are at a premium. 30% smaller than traditional HPAs.
Efficient and Reliable
Meets International Safety Standard EN-60215 and EMC Standard EEC 89/336 to satisfy worldwide requirements.
Easy to Maintain
Modular design and built-in fault diagnostic capability with convenient and clearly visible indicators for easy maintainability in the field.
Worldwide Support
Employs an ultra-high efficiency dual-depressed collector helix traveling wave tube backed by many years of field-proven experience in airborne and military applications. The collector design is optimized for super-cool operation.
Simple to Operate
Backed by over two 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 computer interface, digital metering, pin diode attenuation, optional integrated linearizer for improved intermodulation performance, and BUC option for use with L-band modems.

1Prime power AC line unbalance not to exceed 3%. Excess imbalance may cause an increase in residual RF noise (AM, FM and PM). Phase noise increase is typically 2.5 dB / % imbalance. 2AC current harmonic content: less than 20%, primarily fifth and seventh harmonics. Harmonics must be considered when choosing UPS sources. 3Up to 1250 watts linear power available through optimization of linearizer settings.
