400W Compact Medium Power Amplifier for Satellite Communications X-Band The VZX-6984A4 400 Watt TWT Medium Power Amplifier— high efficiency in a compact package. X-Band Provides 400 watts of power in a 3 rack unit 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 earth station applications where space and prime power are at a premium. Easy to Maintain Modular design and built-in fault diagnostic capability with convenient and clearly visible indicators behind front panel door for easy maintainability in the ﬁeld. Worldwide Support Efficient Employs a high efﬁciency dual-depressed collector helix traveling wave tube backed by many years of ﬁeld-proven experience in airborne and military applications. 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. 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 Meets International Safety Standard EN-60215, Electromagnetic Compatibility 89/336/EEC and Harmonic Standard EN-61000-3-2 to satisfy worldwide requirements. 811 Hansen Way P.O.
