Upping liquid-cooled efficiency

The Maxiva ULXTE is GatesAir’s new family of liquid-cooled, IP-enabled UHF TV transmitters. The line incorporates the latest LDMOS transistors and RF devices, which are responsible for efficiency and power gains. GatesAir has raised overall ULXTE transmitter efficiency from 42 to 46 per cent, which represents a 10 per cent increase.

The 20 per cent power improvement is also a significant operational benefit, allowing broadcasters to get more power out of a smaller transmitter, said the company.

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, ATSC 3.0 and other standards, giving broadcasters an out-of-the-box way 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 wattage requirements at the amplification stage, without affecting signal strength.

Maintenance is streamlined in several ways, including a lightweight footprint that enables true single-engineer maintenance.
