DUT-8422 400W MUDS DVB-T digital transmitter

 

 

 

Product Overview

 

DUT-8422 is a professional 400W DVB-T transmitter which gives sustained power output and with Compact structure design to save space. It supports SFN and MFN, support signal carrier mode and multi carrier mode, support signal channel and broadband transmission.

The frequency range of DUT-8422 is from 470MHz~806MHz. This transmitter has a very high linear and high reliability because it takes high power gain and high linear LDMOS tube amplifier module. And its cooling system is forced cooling. Furthermore it support AGC function, and it can keep sustained power output.

DUT-8422 400W DVB-T transmitter can be widely used in HD/SD digital TV single transmit and broadcasting system.

 

Key features

  • Improve signal transmitting quality
  • Intelligent, modularized amplifier unit, takes high power gain and high linear LDMOS tube amplifier module design
  • Low power consumption super linear design, improve the transmission power of the transmitter, and reduce the nonlinear distortion
  • Support AGC function, with sustained power output, to approve the transmitter have good stability and reliability
  • Support MFN and SFN system
  • Have the fault diagnosis function
  • Intelligent and full digital front panel control, easy operation.
  • LED on the front panel support alarm and signal monitor
  • The switching power supply with wide range of voltage, high efficiency
  • Power amplifier and switching power supply one-on-one configuration, each connected directly inserted, reduce the attachment loss, improve efficiency
  • Designed with cooling fan, cooling system with low consumption and low noise
  • Multi lightning protection design, good protection for whole equipment.
  • 24 hour working unmanned, user friendly design
  • Easy for install, good looking
