1 GT-Series UHF TV Transmitter

2 GT-Series UHF TV Transmitter Features High efficiency Leading-edge LDMOS in Power Amplifier (PA) device Standard PA type : Up to 3% for COFDM and ATSC Doherty PA type : Up to 38% for COFDM Up to 4% for ATSC High power with very small footprint One of the most compact footprints in the same power output model in the industry - High-power (up to 9.9kW) : W 570 x D 000 x H 950 mm - Medium-power (up to 3.kW) : W 570 x D 800 x H 950 mm - Low-power (up to 730W) : W 570 x D 800 x H 8 mm EIA rack-mount sized unit / sub-chassis Downsized and lightened liquid-cooled PA by adopting new-structure cold plate Flexible system configuration Since starting the production of analog television transmitters in 95, Toshiba has provided high-quality and high-reliability in transmission networks all over the world for 0 years. The technology of Toshiba has taken the lead in the broadcasting industry in making a through shift to the digital broadcasting.toshiba is now unveiling the brand-new GT-Series UHF digital TV transmitters that offer high-quality, high-performance, high-reliability, and superior cost-performance to customers worldwide. The GT-Series UHF solid-state digital transmitter has been designed for multi digital TV standards (DVB-T, DVB-T/H, ISDB-T/Tb, ATSC, ATSC-M/H, DTMB and CMMB). By adopting a leading-edge LDMOS technology and a new downsizing feature, GT-Series has achieved up to 5% reduction in footprint, more than 5 points of improved efficiency, and up to 00% increase in power output by a rack, compared to the existing devices. Multi digital broadcasting standards; DVB-T, DVB-T/H, ISDB-T/Tb, ATSC, ATSC-M/H, DTMB/CMMB UHF full band from 470 MHz to 8 MHz Low-cost and scalable system architecture 3 FET blocks and 3 PS blocks mounted in one PA plate EX-exchange, power distribution and TX-Monitor functions in one Control Unit (CU) Higher power output system available by adding racks Various systems such as hot standby, dual-tx, N+ systems Various options; adaptive compensation, touch panel, etc. Easy maintenance Easily removable PA plate Hot-swappable & Plug-in PA plate with built-in power supply Exchangeable FET block and PS block Downsized liquid-cooling system and reduced exchange cost of coolant by closed-circuit Pump replacement available during operation by using dual cooling pump Easy operation Easy operation by CU Monitoring / Control available by external PC (Option) connected to Ethernet or touch-screen (Option) Remote control and monitoring via SNMP Easy installation GT-Series has three models of product lineups; High-power model (Liquid-cooled)/Medium-power model (Air-cooled)/Low-power model (Air-cooled), depending on system requirements. The High-power model achieves up to 9.9kW(before bandpass filter) power output by one rack, and can output higher power by combining two or more racks. High/Medium-power model : 3-phase AC400V ± 5% and 3-phase AC00V ± 5% without AVR Low-power model: single phase AC00V 5% without AVR Easy access to each interface Air-cooled transmitter installable to general-purpose EIA rack Units in GT-Series are designed in EIA rack-mount size. Especially, in Air-cooled models, the installation process is very simple because all the components can be mounted in a general-purpose EIA rack. Reliability Automatic restart within 5 seconds after recovery from blackout Normal operation with VSWR up to.3 Independent drain connectors for PA plate Built-in GPS receiver for SFN (Option)
