VZU-6998VY

      The VZU-6998VY is designed as a 750 Watt TWT medium power amplifier which has the features of high efficiency in an environmentally sealed compact package designed for outdoor operation.
      VZU-6998VY has seven features.The first one is that it could be played in the rain which provides 750 watts of power in a rugged and compact weatherproof package, digital ready,for wideband, single- and multi-carrier satellite service in the 17.3-18.4 GHz frequency band.It would be ideal for transportable and fixed earth station applications.The second one is that it would cost effective and efficient.With mounting at the antenna improves performance through minimized cable losses and saves cost in system design,and also employs a high efficiency, dualdepressed collector helix traveling wave tube,reducing operating costs,it will make the customers feel good.The Third one is it would be reliable.That means it is designed and built to survive in extremely dverse environmental conditions and features increased cooling margin for longer life.The fourth one is that it is simple to operate.With integrated RS422/485 computer interface the users would be easy to know about user-friendly microprocessor-controlled logic.And with digital metering, pin diode attenuation and optional integrated linearizer for improved intermodulation performance.The fifth one is that it is easy to maintain.With mdular design and built-in fault diagnostic capability via remote monitor and control.The sixth one is global applications.It meets international safety standard EN-60215,electromagnetic compatibility 89/336/EEC and harmonic standard EN-61000-3-2 to satisfy worldwide requirements.The last one is it has a worldwide support.The CPI company has a worldwide 24-hour customer support network that includes fifteen regional factory service centers and also has three decades of satellite communications experience.
      Some important specification of VZU-6998VY have been concluded into several points.The first one is about its frequency which should be 17.3 to 18.4 GHz.The secnd one is about its bandwidth which should be 1100 MHz.The third one is about its ambient temperature which should be -40°C to +55°C when operating,including solar loading and -40°C to +75°C when non-operating.
      Four options shoule be noted.The first one is integral linearizer.The second one is remote control panel.The third one is redundant and hybrid power combined systems.The last one is integrated switch control and drive (1:1 or 1:2).
