GATESAIR Maxiva "ULXTwith PowerSmart* 3D
High Efficiency UHF Liquid-Cooled TV Transmitter
: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.
iillH III
iMaxiva ULXT utilizes the latest 50 volt LDMOS amplifier devices, new compact high-efficiency powersupplies and the Maxiva M2X™ exciter with RTAC™. It provides today's broadcaster with unparalleledpower 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.9 9ST ET
This powerful blend of new technologies provides best-in-class performance with respect to
transmitter power efficiency, physical size, performance and features. The modular designallows for simpler installation, infrequent maintenance requirements together with dramatically
reduced total cost of ownership over the life of the transmitter.
Product Features
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
One-to-one power supply to poweramplifier redundancy
Hot-pluggable, small and lightweight (11kg)linear RF amplifier modules and DC powersupplies
Transmitter monitoring and in-depthdiagnostics via easy-to use, front panelcontrols and indicators
Incorporates Maxiva Web-enabled remote
control graphical user interface
Includes front panel LCD screen for displayof transmitter parameters, includingForward Power and Reflected Power
The fully broadband UHF transmitterwith the highest efficiency on the market.
The all-new design includes these energysaving components to reduce Total Cost of
Ownership:
PowerSmart 3D amplifier technology, forbest-in-class power efficiency, broadband
operation and lowest operating costs
High efficiency, compact, hot swappableAC to DC power supplies
Variable speed coolant pumps and heat
exchanger cooling fans maximize system
efficiency
Typical AC to RF efficiency of up to 42% for
ATSC, including cooling system
Typical AC to RF efficiency of up to 38%
for all COFDM TV modulations, includingcooling system
Rugged, reliable design and construction
Digital power levels up to 17.7 kW ATSC,
10.8 kW COFDM TV yields the highestpower density per cabinet
The Maxiva ULXT PowerSmart 3D series
is available from low power to highpower models, suitable for almost anyUHF broadcast application.Designed with future broadcastingneeds in mind, the ULXT
transmitter is capable of multiplemodulation schemes UHF digitaloperation — including ATSC, ATSC
MDTV, DVBT/H, DVB T2, ISDB-Tb andfuture digital standards. Upgradingto newer digital standards is readilyaccomplished to further extend thecapability and life of the transmitter.

Exciter external UPS
Internal or External pump system (for
models up to 5.5 kW COFDM/9.0 kWATSC)
ASI/T2MI over IP (100/1OOOBASET)
Compact Footprint
As the most compact liquid-cooled UHF
transmitter, the Maxiva ULXT is ideal forcrowded, shared transmitter sites. The
Maxiva M2X exciter drive further reducesrack space requirements. The Maxiva
ULXT transmitter reduces facility spacerequirements, 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 and10.8 kW COFDM, fewer amplifier racks arerequired.
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 ServiceCosts
Hot-pluggable, redundant power amplifier(PA) and universal power supply (PS)
modules make on-air servicing easy andeliminate costly service interruptions. Light¬
weight universal PA pallets and universalPS modules facilitate overnight/same-day
shipping for simple, cost-effective sparesholding. With lightweight subassemblies, theMaxiva ULXT eliminates any two-person lift
requirements for routine maintenance andtroubleshooting.
Smooth Upgradeability
The Maxiva ULXT system features the newUAX Compact Class drive, using Maxiva M2X
exciter technology, allowing for a seamlesstransition from any analog standard to
a digital terrestrial standard, or from
an existing digital standard to a futurestandard, such as from DVBT to DVBT2 or
from ATSC to ATSC MDTV.
