UMT DVB-S/S2 Modulator L-Band Module Board 
designed to convert a parallel DVB transport stream 
into a satellite IF signal modulated in accordance with DVB-S, DVB-S2


It can be used to build various converters, modulators, transmodulators and other digital broadcasting equipment. 

The DVB-S / S2 receivers modules, MPEG encoders, ASI-to-DVB TS converters, IP-to-DVB TS receivers compatible with this module can be used as the source of the input stream. 

The RF output signal can be fed to adders, additional filters or directly to television transmitters. 

The main advantages of the module are high parameters of the modulated signal, the possibility of fine tuning, small size and power consumption, which provides greater flexibility of usage.


UMT DVB-S/S2 Modulator L-Band Module Board can be controlled, monitored and adjusted from PC via TCP/IP protocol.

UMT IP Control Module Board (6 or 16 ports) is required for management and monitoring of the Modulator Board.
(can be purchased separately, please see other lots in our eBay store)

Taking into consideration that we (UMT LLC) are developer and system integrator, also do not stop on our technical growth and improvement, 
know that view of all our devices and equipment including their technical parameters may be different from pictures presented on website and parameters listed on each device webpage. 


UMT LLC is a young company which work at the digital telecommunication and TV broadcasting market as a system integrator, developer and manufacturer of the equipment for:

   - DVB communications
   - microwave TV broadcasting systems like MMDS, MVDS and LMDS 
   - radio relay systems of C, Ku K and Ka-bands with high level of channels capacity


We design and manufacture this device. 
So if it is not in stock, handling time can be longer than a few days (usually up to one week).

Please do not hesitate to ask any questions you may have before buying or bidding.
