DUT-8322 DVB-(T) Digital Transmitter (200W-600W)
Outline
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.
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
Multi lightning protection design, good protection for whole equipment.
24 hour working unmanned
Easy to install, user friendly design
