COMPACT 100W Dab Transmitter
ODMD Super compact Multi-channel DAB/DAB transmitter 3 channels in 1 RU
ODMD shifts paradigm in multichannel DAB/DAB transmitters
Up to now, the simultaneous broadcasting of 3 separate DAB ensembles from the same site implied a bulky combination of modulators, power amplifiers, SFN adapters, channel filters and combiners. ODMD wipes all that stuff away from your sites, at a fraction of the cost you can expect from traditional equipment.
Into a single 1RU chassis, ODMD provides you with up to 3 complete DAB/DAB /T-DMB transmitters with independent input, signal processing engine, DAB modulation stages, and an ultra-linear “common mode” 130W high efficiency Doherty amplifier. The generated channels are combined at low level, allowing broadcasters to avoid, in case of operation on adjacent channels, external RF combiners: the ODMD features just a single RF antenna connector, requiring just a single band-pass filter.
The output power can be individually set per each of the channels in use to fit compliance requirements.
ODMD also supports individual SFN operation for each DAB/DAB emission, and features a built-in GPS receiver.
ODMD modular design allows you to buy and install just the number of transmitters you need: at any later stage you’ll be able to expand its capabilities.
Both the power amplifier module and the power supply unit included into the ODMD can be easily and individually replaced while the chassis is on its frame.
Designed for last-mile applications, ODMD saves footprint at transmitter sites and perfectly suits any low power broadcasting application, including road and railway tunnels coverage.
