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
