CPI 2.25 and 2.50 kW SuperLinear tm TWT Amplifiers for Satellite Communications X- Band The TL22XI and TL25XI TWTAs X-Band Up to 2.5 kW (1110 W operating) TWT Compact High Power Amplifiers, featuring high efficiency, small size and integral computer interface. Global Applications 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. Meets International Safety Standard EN-60215 and EMC Standard EEC 89/336 to satisfy worldwide requirements. Efficient and Reliable 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. 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 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. Simple to Operate 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. 811 Hansen Way P.O.
