Maxiva ULXT with PowerSmart 3D TM High Efficiency UHF Liquid-Cooled TV The GatesAir Maxiva ULXT with 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 groundbreaking 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 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. Product Features The fully broadband UHF transmitter with the highest efficiency on the market. The all-new design includes these energy saving components to reduce Total Cost of Ownership: The Maxiva ULXT 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, DVBT/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. PowerSmart 3D amplifier technology, for best-in-class power efficiency, broadband operation and lowest operating costs Field-proven Maxiva M2X exciter technology, allowing easy migration to new digital standards Fast acting, all-digital linear and nonlinear pre- correction, using exclusive Maxiva Real -Time Adaptive Correction (RTAC) Broadband high-efficiency PA modules, with no tuning of adjustments High efficiency, compact, hot swappable AC to DC power supplies One -to- one power supply to power amplifier redundancy Variable speed coolant pumps and heat exchanger cooling fans maximize system efficiency Hot-pluggable, small and lightweight (11kg) linear RF amplifier modules and DC power supplies Typical AC to RF efficiency of up to 42% for ATSC, including cooling system monitoring and in-depth diagnostics via easy-to use, front panel controls and indicators Typical AC to RF efficiency of up to 38% for all COFDM TV modulations, including cooling system Rugged, reliable design and construction Digital power levels up to 17.7 kw ATSC, 10.8 kw COFDM TV yields the highest power density per cabinet Connecting What s Next +1.800.622.0022 Incorporates Maxiva Web-enabled remote control graphical user interface Includes front panel LCD screen for display of transmitter parameters, including Forward Power and Reflected Power www.gatesair.com

This new amplifier design utilizes the latest 50 volt LDMOS device technology to deliver a dramatic increase in power density, lower operating costs and reduced cost of ownership over the life of the transmitter. Compact Footprint As the most compact liquid- cooled UHF transmitter, the Maxiva ULXT is ideal for crowded, shared transmitter sites. The Maxiva M2X exciter drive further reduces rack space requirements. The Maxiva ULXT transmitter reduces facility space requirements, simplifies installation, lowers shipping costs and allows for easier maintenance. Highest Power Density The Maxiva ULXT provides the highest power density per rack in a UHF transmitter. With power levels up to 17.7 kw ATSC and 10.8 kw COFDM, fewer amplifier racks are required. Global Monitoring and Control The Maxiva ULXT transmitter can be controlled from anywhere in the world with an intuitive browser-based GUI or SNMP over TCP/IP via a telecom or network connection with password protection. Improved Uptime and Reduced Service Costs Hot-pluggable, redundant power amplifier (PA) and universal power supply (PS) modules make on-air servicing easy and eliminate costly service interruptions. Lightweight universal PA pallets and universal PS modules facilitate overnight/same-day shipping for simple, cost-effective spares holding. With lightweight subassemblies, the Maxiva ULXT eliminates any two-person lift requirements for routine maintenance and troubleshooting. Smooth Upgradeability The Maxiva ULXT system features the new UAX Compact Class drive, using Maxiva M2X exciter technology, allowing for a seamless transition from any analog standard to a digital terrestrial standard, or from an existing digital standard to a future standard, such as from DVB T to DVB T2 or from ATSC to ATSC MDTV.
