DVB-T digital UHF transmitter

Outline        

 

The DUT-8313 digital TV transmitter (In-room type) is the newest digital TV transmitter product of our company, which is capable of supporting network organizations of single frequency net and multi-frequency net and supporting single carrier mode and multi-carrier mode. Besides, DUT-8313 also supports the transmitting methods of single channel and broad band; and it provides with band width of 470MHz-566MHz and 606MHz-806MHz. Furthermore, the DUT-8313 is composed of an import power amplifier with high gain and high linearity LDMOS tube, which greatly increases the linearity and reliability of the product. And because of the AGC function of DUT-8313, the stability of output power, the reliability and performance of the product are excellent.
DUT-8313 digital TV transmitter (In-room type) can be widely used in HDTV/SDTV digital TV signal transmitting or broadcasting system as well as digital broadcasting.
