Overview
DUT-8323 is a professional 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. Key Features: 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; Support AGC function with sustained power output to allow the transmitter; a good stability and reliability; Support MFN and SFN system; Support fault diagnosis function; Full digital front panel control, easy operation.; LED on the door supporting alarm and signal monitor; Stabilized-power supply with wide range of voltage and high efficiency; Cooling system with low consumption and low noise Specifications: Input reflection loss; RF output power
