Outline

FUTV-9451 is a professional DVB-T digital transmitter researched and developed by FMUSER, which gives sustained power output. Its compact structure design has greatly saved space for your room. It is applicable to both SFN and MFN network modes and supports both signal-carrier mode and multi carrier-mode. Signal channel and broadband transmission are supported.
The frequency range of FUTV-9451 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.
FUTV-9451 DVB-T digital transmitter can be widely used in HD/SD digital TV signal transmitting and broadcasting system.
