Product Overview
ET-MT transmitters are professional DVB-T/T2 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, ET-MT 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
- Multi lightning protection design, good protection for whole equipment.
- 24 hour working unmanned
- Easy to install , user friendly design
