We are featuring the products that won the Radio World Best of Show Award at the 2025 IBC Show. Winners were chosen by a panel of engineers and RW editorial staff for their innovation, feature set, cost efficiency and performance in serving the industry.
GatesAir said its modernized DAB/DAB+ transmitter architecture, which includes the integration of new transistor technology, increases efficiency for low- to medium-power transmitters.
Efficiency can be increased by approximately 5 to 10 percent, depending on the transmitter’s power level.
A design update that GatesAir revealed at the IBC Show includes new adjustable-voltage supplies that minimize power consumption, featuring software algorithms to manage power supplies. As DAB and DAB+ frequencies can carry up to 18 channels, the transmitter can be configured to optimize bitrates, voltages and more for highly signal-dense frequencies.
GatesAir’s new high-efficiency DAB+ transmitter architecture crosses several production lines, including VAXT, VAX-OP and PMTX-1 outdoor transmitters, covering both air-cooled (from 25 watts) and liquid-cooled models (up to 10kW).
GatesAir’s DAB+ redundancy concepts also support 1+1 redundancy with or without switchover units, feature redundant inputs for switching between networks and support redundant AC/LC cooling.
