  • Liquid cooled

The Elti®TERX family of VHF/UHF digital transmitters combine Elti’s reputation for robust equipment with the latest digital technology available from DVB area and the latest solid state LDMOS technology. The Elti®TERX family is robust, fail-safe, with high efficiency, designed for digital TV networks, featuring intelligent redundancy concepts, fully configurable for your indoor/outdoor applications.


The exciter is housed in a ultra compact 19” 1U rack mount with the AB class amplifier that provides up to 50 W of UHF and VHF output power. The built-in COFDM modulator features up to 4 ASI inputs and 2 IP stream inputs, and provides 2k up to extended 32k IFFT operation mode (up to 8k for DVB-T). If the primary transport stream source fails the exciter can seamless switch between the four ASI and IP inputs manually or automatically.

Power Amplifier

External amplifiers are available in models supplying 250 W and 500 W of UHF output power and 600 W of VHF output power. All amplifiers are designed for broadband and employ the latest state of the art LDMOS technology to guarantee linearity, compact design and high efficiency for minimizing operational costs. Self-protection circuits assure continuous operation and uninterrupted service in sight of minimizing operational costs.

Doherty Power Amplifier

Thanks to the Doherty amplifier concept, Elti’s new compact design UHF amplifiers makes terrestrial broadcasting extremely efficient. Due to higher efficiency into comparison to classical amplifier design, new amplifier series brings to network operator cost reductions over the entire system lifetime. Amplifier is available in a compact 19’’ only 2U rack mount, provides 1.0 kW of output power and is available in air and liquid cooling solutions. Scalable and flexible configurations allows now higher power density into single rack.

*TERX has option to work as DualCast transmitter (analogue/DVB). More information in product datasheet.
