| 750W Compact High Power Amplifier for Satellite Communications DBS-Band The VZU-6997CY 750 Watt TWT High Power Amplifier-- high efficiency in a compact package. DBS-Band 750W Compact High Power Amplif ier Compact Easy to Maintain Provides 750 watts of power in a 5 rack unit package, digital ready, for wideband, single- and multi-carrier satellite service in the 17.3-18.4 GHz frequency band. Ideal for transportable and fixed earth station applications where space and prime power are at a premium. Efficient Modular design and built-in fault diagnostic capability with convenient and clearly visible indicators for easy maintainability in the field. Worldwide Support Employs a high efficiency dual-depressed collector helix traveling wave tube backed by many years of field-proven experience in airborne and military applications. Simple to Operate Backed by over three 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 and optional integrated linearizer for improved intermodulation performance.
