Features and advantages

TXTU-150-2-N – a new cost-effective solution added to the DVB-T/H transmitter family “Innovation-2009”. New dimension in compactness is achieved due to the use of the latest generation of transistors and innovative air cooling system. With the output power of 250 W r.m.s., the transmitter has a height of only 3U (134 mm) and a weight of 24 kg.

The amplifier integrated ASI coupler and automatic redundancy switch allow for supplying the transmitter in configuration with 100% automatic redundancy of exciters (TXTU-150-R-2-N).

In addition, the embedded control system enables organizing remote monitoring and controlling of main parameters, which makes it a perfect solution for unattended transmission centers.
