MAXIVA™ UAXTE
Optimized for International Markets
The Maxiva UAXTE utilizes the latest generation 50 volt LDMOS amplifier devices, new compact high-efficiency power supplies and the Maxiva Compact series exciter/driver along with real-time adaptive correction (RTAC) for outstanding signal performance. The Maxiva UAXTE power amplifiers have been optimized to provide the best possible performance and efficiency for both ATSC 1.0 and ATSC 3.0. The UAXTE transmitter is rate for identical average power levels for both modulations, assuring a simple and cost-effective upgrade path for future ATSC 3.0 operation. The modular design further simplifies installation and reduces maintenance costs, dramatically lowering the total cost of ownership over the transmitters life-cycle.
The Maxiva UAXTE with PowerSmart Plus is an efficiency-optimized UHF transmitter. This all-new design includes several energy saving features.
Up to 44% AC-to-RF efficiency
Simple and cost-effective upgrade path from ATSC 1.0 to ATSC 3.0 at the same power level.
Efficiency-optimized – for highest efficiency and lowest cost of ownership

Maxiva™ UAXT Ultra-Compact / VAXT Ultra-Compact
Maxiva™ UAXT Ultra-Compact / VAXT Ultra-Compact
The new Maxiva UAXT & VAXT Ultra-Compact family of UHF solid-state Transmitters / Transposers (Translators) and on-channel Gap Fillers expands upon the proven foundation of GatesAir low-power systems and PowerSmart® high-efficiency technology. It provides today's digital broadcaster with a suite of compatible products to accommodate any coverage application, along with unmatched performance, reliability and quality.
The Maxiva Ultra-Compact family further extends the capabilities of the Maxiva series, providing a single family of transmission products capable of satisfying any coverage architecture. The Maxiva Ultra-Compact provides pre-filter power levels up to 1,000W, in exceptionally compact and space-saving 1RU, 2RU and 3RU packages.
Designed for both analogue and digital broadcasting, the Maxiva UAXT/VAXT Ultra-Compact is a platform available in Transmitter, Transposer or SFN Gap Filler configurations for DVB-T, DVB-T2, ATSC, ISDB-Tb, DAB/DAB+ and NTSC/PAL analogue networks. The Maxiva Ultra-Compact Series provides an ideal solution for extending market coverage and filling in coverage gaps in challenging situations, including busy urban areas that require greater building penetration.
The Maxiva UAXT & VAXT Ultra Compact family of Transposers and on-channel Gap Fillers provide efficient and reliable re-broadcast of the received signal in a space saving, reliable and robust package. The Gap Filler configuration adds a powerful echo cancellation feature to deliver exceptional on-channel performance. For ATSC (8-VSB) Gap Filler applications, a new on-channel Spectrum Restorer utilizing EDOCR technology provides unsurpassed performance. This combination of products enables broadcasters to address any network coverage requirement.
