GatesAir has announced the release of a new DAB+ transmitter infrastructure.
The enhancements to its family of Maxiva digital radio and VHF TV products will be unveiled at IBC2025.
The company says the modernized architecture improves its efficiency by approximately 25 percent, while the adjustable voltage capabilities of its new power supplies help minimize power consumption.
The company said it began its efforts toward more efficient transmitter design almost 20 years ago with its PowerSmart architecture, which consists of internal power amplifiers, power supplies and other components that improve energy use and operating costs.
It said new transistor technology now helps increase efficiency for low- to medium-power transmitters, thanks in part to technology that allows for reduced modulation error ratios (MER) during operation. It enables a 5 dB reduction of a typical DAB+ MER level, which translates to maximum efficiency levels of 50 percent or higher.
The DAB+ transmitter architecture is included across several of its production lines, including VAX-T and VAX-OP transmitters, PMTX-1 outdoor transmitters and MultiD multicarrier systems. It affects both air- and liquid-cooled models.
The transmitters optimize EDI connectivity for enterprise-level contribution and distribution, GatesAir says, with access to an Intraplex ultra-low-latency IP transport solution for large DAB networks.
