DVB-T digital UHF VHF transmitter
Outline
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.
Features
