Description
DUT-8313 (800W-1200W) DVB-T/(T) Digital Transmitter
1.1 Outline
DUT-8313 is a professional DVB-T/(T) digital transmitter with 800W/1000W/1200W power optioanal. Its compact structure design has greatly saved space for your room.
The frequency range of DUT-8313 is from 470MHz~806MHz. This transmitter has a 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.
Dexin is always ready to meet customer requirements by making it available to output signal carrier or multi carrier, adapt to signal channel and broadband transmission..
1.2 Key Feature
- telligent and modularized amplifier unit, takes high power gain and high linear LDMOS tube amplifier module design
- Low power consumption and super linear design to improve the transmission power, and reduce the nonlinear distortion
- Support AGC function with sustained power output to allow the transmitter a good stability and reliability
- Support MFN and SFN system
- Support fault diagnosis function
- Full digital front panel control, easy operation.
- LED on the door supporting alarm and signal monitor
- Stabilized-power supply with wide range of voltage and high efficiency
- Cooling system with low consumption and low noise
- Multi lightning protection measures, good protection for whole equipment.
- 24-hour working unmanned, user friendly design
- Easy to install, elegant appearance
