RE9000MP series - RE9301

Medium power Digital UHF Transposers - DVB-T/H/T2, ISDB-T/TB, ATSC


Brief Description

Medium power multistandard gap fillers/transposers of RE9000MP series are equipped with the latest technology in signal processing. The power amplifiers are based on LDMOS-50 volt. transistors characterized by high linearity and high power density, providing excellent energy efficiency.

They are fully programmable and can be quickly configured to different channels. Its high selectivity allows them to work smoothly in presence of adjacent channels and can incorporate an optional digital echo canceller that limits effectively the ripple caused by an inadequate isolation between antennas. All the equipment can be monitored remotely via potential-free contacts, an SNMP agent or a Web Browser.

Its compact and modular design, as well as its high energy efficiency facilitate the installation and maintenance, reducing the total cost over the life of the transposer for the broadcast operator.
