GatesAir Announce Lineup For Amsterdam Show

GatesAir will demonstrate its high-efficiency transmitters and software-defined exciter at IBC2016, alongside IP transport capabilities for DVB-T2 digital TV systems, Stand 8.C30.

The product line includes the Maxiva UHF DTV transmitters with PowerSmart Plus and the Maxiva XTE exciter. They minimise space consumption and reduce the overall carbon footprint of the RF plant. Designed for the green economy, PowerSmart Plus is a next-generation transmitter architecture that can raise AC to RF efficiencies up to 50% for ATSC and DVB-T2 transmitters.

"With design advancements like the recent integration of high-efficiency power amplifiers, our PowerSmart Plus transmitter architecture goes above and beyond the efficiency gains attained by our previous energy-saving technologies," said Rich Redmond, Chief Product Officer, GatesAir.

The ultra-high efficiency enables GatesAir Maxiva ULXT liquid-cooled and UAXT air-cooled UHF DTV transmitters to operate with greater efficiency. Compared to legacy air-cooled UHF transmitters, broadcasters can see up to 170% greater efficiency. In turn, this results in a significant cost reduction.

"Our customers can actually measure this new efficiency benchmark in their RF plant's significantly lower energy consumption, resulting in lower power bills. And we can show prospective customers how investing in PowerSmart Plus can lead to operational savings that contribute to a rapid return on investment," added Redmond.

Utilising PowerSmart Plus and the Maxiva XTE software-defined exciter, GatesAir's Maxiva ULXT liquid-cooled and UAXT air-cooled transmitters provide the high efficiency and performance. Along with reducing energy use, all Maxiva transmitters provide the benefits of broadband amplification to simplify maintenance and modulation adjustments, while requiring fewer spare parts. These transmitters are ready for emerging signal processing challenges including advanced wireless IP-based transport capabilities, 4K and UHD resolution content delivery, and support for advanced DTV standards such as DVB-T2, ISDB-Tb and ATSC 3.0.

The UAXT is the newest member of the Maxiva range and offers air-cooled operation at higher power levels. At the NAB Show 2016, GatesAir expanded the Maxiva line with the new UAXT-12 (10.8 kW) and UAXT-16 (14.4 kW) models; two power levels that were previously not available in the UAXT range. IBC2016 marks the international debut of the higher power UAXT models.

Also at IBC2016, GatesAir will demonstrate its software-defined Maxiva XTE exciter. Supporting all analog and digital TV standards, the XTE provides advanced signal processing, throughput and IP transport capabilities needed to deliver highquality video/audio content and data associated with today's – and future – digital broadcast standards. The 1RU XTE also leverages GatesAir's latest software innovations for signal performance, including its Real Time Adaptive Correction (RTAC) technology, and offers an in-the-field upgrade path to support future transitions and standards.

GatesAir's RTAC technology incorporates digital adaptive pre-correction algorithms to overcome the lack of linearity in standard amplification techniques. The XTE's built-in RTAC software preserves long-term reliability for optimised over-the-air signal performance and compliance. Pre-distortion affecting performance in simpler mathematical models is eliminated, resulting in a cleaner and stronger signal.

"The signal correction characteristics are crucial to addressing the many artifacts and imperfections that are common in multichannel DTV broadcasting, including but not limited to a sharp improvement in modulation error ratio (MER)," said Redmond. "This is a clearly defined problem worldwide that XTE goes a long way in solving for our customers."

"To remain competitive, broadcasters worldwide share the goal of adopting the most energy efficient UHF DTV transmission products to contain their costs and preserve the environment," concluded Redmond. "Our Maxiva transmitters, XTE exciter and PowerSmart Plus technology have all been designed to deliver a compelling operational value proposition without compromising quality."
