GatesAir is set to unveil its Maxiva ULXTE liquid-cooled transmitters at IBC.

The Maxiva ULXTE, GatesAir’s new family of liquid-cooled, IP-enabled UHF TV transmitters, increase overall system efficiency, while increasing transmitter power levels by up to 20%.

GatesAir will demonstrate the ULXTE, emphasizing its RF performance and ability to reduce costs associated with operational expense and maintenance.

The ULXTE incorporates the latest LDMOS RF devices, which are responsible for the efficiency and power gains. GatesAir has raised overall ULXTE transmitter efficiency up to 45%, and improved transmitter power by 20%. The latter offers a significant operational benefit by allowing broadcasters to get more power out of a smaller transmitter, substantially improving cost per watt.

The ULXTE also integrates GatesAir’s latest-generation Maxiva XTE exciter. Featuring a software-defined modulator, the XTE includes native IP inputs and eliminates the need to retrofit transmitters with additional gear to enable network connectivity for DVB-T2, DVB-T2 Lite, DVB-T, ISDB-T, ATSC 3.0 and other standards, giving broadcasters an out-of-the-box solution to simplify the input and output of multimedia services via a local- or wide-area IP network. The XTE-driven modulation reduces costs and power consumption by lowering DC power requirements at the amplification stage, while improving signal quality parameters.

“The ULXTE brings the exceptional RF performance and signal strength and quality to broadcasters who want the additional cost-savings that liquid-cooling offers inside the RF plant, particularly in climates that would require very high cooling loads for air-cooled transmitters,” said Rich Redmond, chief product officer, GatesAir. “These enhancements, along with a reduced burden in system maintenance and monitoring, further enhance reliability and lower total cost of ownership across large transmitter networks.”
