GatesAir introduces the Maxiva XTK, a new cost-efficient software-defined TV exciter developed for the global ATSC 3.0 broadcast community.
Following the legacy of the Maxiva XTE, the XTK provides advanced ATSC 3.0 processing through a modern FPGA-based platform, reducing costs while improving broadcasting efficiency.
Product Features
The 1RU Maxiva XTK is a fully productized version of GatesAir’s award-winning ATSC 3.0 modulation software introduced at NAB Show 2025. The XTK is included in the latest high-efficiency TV transmitters, including the UATK-OP and UATK low-power UHF series, and extends ATSC 3.0 capability to VATK-OP and VATK low-power VHF transmitters. Its backwards-compatible design ensures operability with previous Maxiva UHF/VHF transmitters and many Harris legacy DTV systems.
The exciter’s software-defined architecture optimizes signal performance and allows transitions between digital standards through firmware updates. Additionally, the XTK supports the ISDB-Tb standard, making it suitable for Brazilian broadcasters preparing for ATSC 3.0 transitions. It is also standard in GatesAir’s PMTX-1-UK outdoor transmission systems, widely deployed globally for flexible installation and low-maintenance operation.
Statement from GatesAir
“We see the XTK as the next step in GatesAir’s software-defined exciter innovation, building on the proven reliability and flexibility of our XTE platform,” said Steve Rossiter, TV Systems Applications Engineer at GatesAir. “Broadcasters now have a forward-looking solution that can be deployed across our latest Maxiva systems while remaining fully compatible with earlier-generation Maxiva transmitters and legacy systems. We designed the XTK to deliver the processing power, precision, and upgraded flexibility that today’s ATSC 3.0 networks demand.”
