Maxiva™ MultiD
Super-compact multi-channel DAB/DAB+ transmitter
OVERVIEW
GatesAir's Maxiva MultiD shifts the paradigm in multi-channel DAB/DAB+ transmitters.
Until now, 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. The GatesAir Maxiva MultiD dramatically reduces the number of items required, at a fraction of the cost you can expect from traditional equipment.
Within a single 1RU chassis, MultiD 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” 150W high-efficiency Doherty amplifier. Low-level RF signals are combined, allowing broadcasters to avoid, in case of operation on adjacent channels, external RF combiners: the MultiD features just a single RF antenna connector, requiring only a single band-pass filter.
The RF output power can be individually adjusted and set for each channel, to meet compliance requirements. MultiD also supports individual SFN operation for each DAB/DAB+ emission and features a built-in GPS receiver.
GatesAir’s MultiD’s modular design allows you to buy and install only the number of transmitters that you currently need. In the future, it can be easily upgraded to meet your new requirements.
Both the power amplifier module and the power supply unit included with the MultiD can be easily and individually replaced while the chassis is on its frame
Designed for last-mile applications, MultiD saves footprint at transmitter sites and perfectly suits any low power DAB/DAB+ application, including road and railway tunnel coverage.
