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.
