DUT-8322 (600W) DVB-T Digital Transmitter

1.1 Outline

DUT-8322 is a professional DVB-T digital transmitter newly developed by DEXIN, which gives medium (600W) and sustained power output. Its compact structure design has greatly saved space for your room. It supports SFN and MFN network mode, output with both signal carrier mode and multi carrier mode, and supports signal channel and broadband transmission.

The frequency range of DUT-8322 is from 470MHz~566MHz, 6060MHz~806MHz. This transmitter has a very high linear and high reliability as it takes high gain and high linear LDMOS tube amplifier module. Furthermore, it supports AGC function to keep sustained power output.

DUT-8322 600W DVB-T digital transmitter can be widely used in HD/SD digital TV signal transmitting and broadcasting system.
