DAYTAI 1.5KW-3KW DVB-T Digital Transmitter,(DT-DVB-T-DT3KW) is a professional DVB-(T) digital transmitter developed ,
which gives sustained power outpu5t with 1500W/2000W/2500W/ 3000W optional. Its compact structure design has greatly
saved space for your room.The frequency range of DT-DVB-T-DT3KW 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.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
⊙Support MFN and SFN system
⊙Easy to install, elegant appearance
⊙Support fault diagnosis function
⊙Full digital front panel control, easy operation.
⊙24-hour working unmanned, user friendly design
⊙LED on the door supporting alarm and signal monitor
⊙Cooling system with low consumption and low noise
⊙Stabilized-power supply with wide range of voltage and high efficiency
⊙Multi lightning protection measures, good protection for whole equipment.
⊙AGC function with sustained power output to allow the transmitter a good stability and reliability
⊙Intelligent 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
