DVB-T Digital Transmitter (1KW-3KW)

Short Description:

DVB-(T) digital transmitter developed by DEXIN, which gives sustained power output with 1500W/2000W/2500W/3000W optional. Its compact structure design has greatly saved space for your room.

The frequency range of DUT-8323 is from 470MHz~806MHz. This transmitter has a very 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.
