VZX-6987V7

      The VZX-6987V7 is a 750 Watt TWT medium power amplifier.VZX-6987V7  is designed for outdoor operation because of high efficiency in an environmentally sealed compact package.VZX-6987V7  could paly in the rain,also cost effective and efficient.VZX-6987V7  would 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.So that would be ideal for transportable and fixed satcom uplink applications.Through minimized cable losses and saves cost in system design,mounting at the antenna improves performance.VZX-6987V7  is designed and built to survive in extremely adverse environmental conditions,that increased cooling margin for longer life and also make VZX-6987V7 reliable.VZX-6987V7  meets international safety standard EN-60215,electromagnetic compatibility 89/336/EEC and harmonic standard EN-61000-3-2 to satisfy worldwide requirements.That meas it will be very safe.Also the user could operate it easily.It is also easy to maintain.The worldwide service is very good and user would benefit from it.
      VZX-6987V7  has six features.The first one is integral linearizer.The second one is remote control panel.The third one is redundant and power combined subsystems.The fourth one is external receive band reject filter (increases loss by a minimum of 115 dB at 7.25 to 7.75 GHz).The fifth one is block upconverter(950 - 1450 MHz).The last one is higher operating temperature limit (to 65°C including solar loading).
      some important data specifications about VZX-6987V7  have been concluded into five points.The first one is that its frequency would be within 7.9 - 8.4 GHz.The second one is that its bandwidth would be 500 MHz.The third one is about ambient temperature which should be within -40°C to +55°C operating(including solar loading),and also should be within -40°C to +75°C non-operating.The fourth one is that its relative humidity would be 100% condensing.The last one is that its altitude would be 10,000 ft. with standard adiabatic derating of 2°C/1000 ft. operating,and 50,000 ft. non-operating.
