Overview

DEXIN DUT-8322 transmitters are professional DVB-(T) transmission system which give sustained power output and with compact structure design to save space. It supports to work in SFN and MFN system. It can work with single-carrier mode and multi-carrier mode, and support single channel and broadband transmission. This transmitter has a very high linear and high reliability as it takes high power gain and high linear LDMOS tube amplifier module. With its good reputation at home and abroad, DUT-8322 transmitters have been widely used in HD/SD digital TV single transmit and broadcasting system. Key Features:  Improved 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;  LED on the front panel supporting alarm and signal monitor;  Air cooling system with low consumption and low noise
