Maxiva™ UAX AirCooled UHF Multimedia TV Transmitter The Maxiva™ UAX aircooled UHF solid state transmitter incorporates PowerSmart® and Maxiva M2X™ multimedia exciter technologies to provide today’s broadcaster unmatched performance, reliability and quality. Designed with future broadcasting needs in mind, the Maxiva UAX transmitter is a single transmitter platform capable of DVBT/H, DVBT2, ATSC, ATSC Mobile DTV, ISDBTb, CMMB, CTTB or other digital standards. For prefilter power output requirements up to 2.5 kW COFDM, Hotpluggable aircooled linear RF amplifier modules and power supplies for simplified maintenance Modular central control system for straightforward monitoring and indepth diagnostics Webenabled remote graphical user interface (GUI) 2.5kW 8VSB, and 3.75 kW analog, the Maxiva UAX Product Details transmitter is capable of serving broadcasters needs for efficient, easy to maintain transmitter systems. The UAX utilizes GatesAir platform technologies such as the Maxiva Increased Density and Efficiency via GatesAir M2X multimedia exciter, PowerSmart technology and 50v PowerSmart Technology LDMOS amplifier devices. This powerful blend provides best Featuring PowerSmart technology in its transmitter inclass performance with respect to transmitter RF architecture, the Maxiva UAX line offers superior power and performance, efficiency, size, and upgradeability. efficiency. New 50volt LDMOS device technology delivers a dramatic increase in power density, lower operating costs and reduced cost of ownership over the life of the transmitter. Product Features PowerSmart technology, for bestinclass power efficiency and lowest operating costs Improved Uptime and Reduced Service Costs Redundant PA and universal power supply (PS) modules simplify onair servicing and eliminate costly interruptions. Rugged, reliable design and construction Lightweight pallets and modules facilitate overnight/sameday Digital and analog power levels up to 2.5 kW and 3.75 kW, shipping for simple, costeffective spares holding. The Maxiva respectively (before filter) Maxiva M2X exciter technology, allowing easy migration from analog to digital or between different standards RealTime Adaptive Correction (RTAC™) technology is UAX transmitter also supports replacement of pretuned amplifier pallets in the field, eliminating the need for complex tuning after FET replacement. included with every system Fully broadband power amplifier (PA) modules — 470 to 862 MHz 1:1 PA module to power supply (PS) redundancy 1 Connecting What's Next +1.800.622.0022 © 2014 GatesAir © 2014 GatesAir Maxiva™ UAX Maximized Coverage with the Maxiva M2X Exciter Utilizing the GatesAir Maxiva M2X multimedia exciter, the Maxiva UAX transmitter takes digital and mobile TV to the next level. Our digital exciters have logged more hours in real time broadcast than all others combined. The Maxiva M2X exciter provides a flawless signal with complete technical and regulatory compliance for tube and solidstate digital transmitters. Maxiva M2X supports a wide range of global digital standards including ATSC, ATSC Mobile DTV, DVBT/H, ISDBTb, ISDB Tb with remultiplexing/restamping option, FLO, CTTB, CMMB and a range of analog TV standards, including NTSC and PAL. It allows for a smooth conversion to digital transmission, and this flexibility, coupled with the exclusive RealTime Adaptive Correction (RTAC) technology incorporated in the exciter, provides superior performance. Compact Footprint Suited for crowded, shared transmitter sites, the Maxiva UAX transmitter reduces facility space requirements and simplifies installation. Powerful, Straightforward Monitoring and Control The main system control is located in the lowpower unit and communicates with each amplifier bay that has independent protection and control capabilities. Each power amplifier (PA) module has dedicated control and monitoring to support on/off functionality and alarms for reflected power, temperature and current overloads. For maximum functionality, all dual drive Maxiva UAX systems include a Transmitter Control Unit (TCU). The TCU includes two parallel levels of operational support: a main microprocessor based controller and a backup, or “life support” controller. The main controller provides a frontpanel, color touchscreen display, SNMP communications support and IP connectivity via the builtin Web GUI. Ideal for network operations, the control system can be accessed from anywhere in the world via TCP/IP over a telecom or network connection. The backup controller provides minimal control and monitoring of the transmitter platform, using a small number of parallel signals, simple interface controls and front panel controls and indicators. 2 Connecting What's Next GatesAir.com Maxiva™ UAX +1.800.622.0022 © 2014 GatesAir Proprietary and confidential Maxiva™ UAX Images/Diagrams UAX15AN UAX100 Digital/UAX75/150AN UAX250 Digital/UAX375AN UAX500 Digital/UAX750AN 3 Connecting What's Next GatesAir.com Maxiva™ UAX +1.800.622.0022 © 2014 GatesAir Proprietary and confidential Maxiva™ UAX UAX1000 Digital/UAX1500AN 4 Connecting What's Next GatesAir.com Maxiva™ UAX +1.800.622.0022 © 2014 GatesAir Proprietary and confidential Maxiva™ UAX UAX2000 Digital/UAX3000AN Specifications Specifications and designs are subject to change without notice General Frequency 470 to 862 MHz, in 1 Hz steps Range Transmission ATSC, DVBT, DVBT2, ISDBTb, Analog, CTTB Standards Channel 6, 7 or 8 MHz (system dependent) Bandwidth Rated Power See chart below Output Output Power 0 to 10 dB Reduction Range RF Load 50 ohms Impedance VSWR Protected against open or short circuit, all phase angles.
