Game Changer Award Finalist 2016: PowerSmart® Plus
OVERVIEW

The GatesAir Maxiva™ ULXT with PowerSmart® Plus / PowerSmart® 3D is a liquid-cooled transmitter that powers over-the-air delivery across the UHF television spectrum. Built on the next generation of GatesAir’s ground-breaking green transmission architecture, Maxiva transmitters offer today’s digital broadcaster compact, energy-efficient solutions to reliably deliver rich, high-quality multi-format content to viewers at home or on the move, and reduce Total Cost of Ownership.

Maxiva ULXT utilizes the latest 50-Volt LDMOS amplifier devices, new compact high efficiency power supplies and the Maxiva M2X™ exciter with RTAC™.  It provides today’s broadcaster with unparalleled power efficiency and outstanding signal performance. In fact, a single ULXT PowerSmart Plus / PowerSmart 3D amplifier model covers the entire frequency range of UHF band IV/V, without the need for adjustment or tuning of any kind. This powerful blend of new technologies provides best-in-class performance with respect to transmitter power efficiency, physical size, performance and features. The modular design allows for simpler installation, infrequent maintenance requirements together with dramatically reduced total cost of ownership over the life of the transmitter.

The Maxiva ULXT PowerSmart Plus / PowerSmart 3D series is available from low power to high power models, suitable for almost any UHF broadcast application.

Designed with future broadcasting needs in mind, the ULXT transmitter is capable of multiple modulation schemes UHF digital operation — including ATSC, ATSC MDTV, DVB-T/H, DVB T2, ISDB-Tb and future digital standards.  Upgrading to newer digital standards is readily accomplished to further extend the capability and life of the transmitter.
