GatesAir has brought to market its latest high-efficiency RF product with the release of a new transmitter infrastructure for its entire range of DAB/DAB+ transmitters.
To be introduced at IBC2025 in September, the modernized architecture is designed to improve efficiency percentages by upward of 50%.
The integration of new transistor technology increases efficiency for low to medium power transmitters. “DAB and DAB+ frequencies can carry up to 18 channels, and our new high-efficiency architecture for five transmitter lines provides our customers with an adjustable palette to optimize bitrates, voltages and more,” GatesAir VP of Technology Ray Miklius said. “We are effectively applying our market-leading innovations in modulation ratios and energy efficiency to deliver true cost and labor savings for digital radio broadcasters and network operators seeking real ROI for their present and future DAB investments.”
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). The new transmitters optimize EDI connectivity for enterprise-level contribution and distribution, with access to an Intraplex ultra-low-latency IP transport solution for large DAB networks. That product leverages GatesAir’s IPConnect transport technology to leverage SRT transport instead of ETI or satellite-based distribution. The Intraplex technology ingests EDI streams and wraps them in the SRT protocol for transport to one or more points across the DAB network, with the added protection of network path redundancy through GatesAir’s Dynamic Stream Splicing (DSS) software to enhance stream resilience.
GatesAir will demonstrate its latest DAB+ high-efficiency transmitters, Intraplex IP transport and networking solutions and Flexiva FM transmitters at Stand 8.B75 at the RAI Amsterdam from September 12-15.
