| 750W Outdoor TWT Medium Power Amplifier for Satellite Communications X- Band The VZX-6987V7 750 Watt TWT Medium Power Amplifier -- high efficiency in an environmentally sealed compact package designed for outdoor operation X-Band Plays in the Rain Easy to Maintain 750W Outdoor TWT Medium Power Amplif ier Provides 750 watts of power in a rugged and compact weatherproof package, digital ready, for wideband, single- and multi-carrier satellite service in the 7.9 - 8.4 GHz frequency band. Ideal for transportable and fixed satcom uplink applications. Cost Effective and Efficient 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 Mounting at the antenna improves performance through minimized cable losses and saves cost in system design. Employs a high efficiency, dualdepressed collector helix traveling wave tube, reducing operating costs. Reliable Backed by over three decades of satellite communications experience, and CPI's worldwide 24-hour customer support network that includes fourteen regional factory service centers. Designed and built to survive in extremely adverse environmental conditions 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. 811 Hansen Way P.O.
