ABE MTX Medium Power

The ABE MTX Medium Power Transmitters series of medium power TV transmitters is the ultimate in technology, quality and performance, designed to achieve the benefits of digital modulation systems to generate analogue and digital emissions (DVB-T2, DVB-T / H, ISDB- T / Tb, ATSC and other standards).

The MTX series combines the extreme efficiency and reliability of the wide band LD-MOS amplifiers with state-of-the-art technological solutions.

Main advantages

• Open platform to meet current and future needs
• The Maximum in terms of technology, quality, performance and reliability
• Low cost of capital, low management and maintenance costs
• Full range of options and configurations to meet every need

The MTX Series of Low Power Transmitter – Transposer is a professional product line, suitable for the integration in both analog and digital TV transmission networks (DVB-T/H, DVB-T2, ISDB-T/Tb and others, operating both MFN and SFN).

The equipment is fully contained in a single 19” rack drawer and is capable, with its internal RF power amplifier, to provide up to 800Wavg digital output (higher power on request) or 1500Wp.s. in analog mode.

Featuring modular construction – with easily removable modules/boards having RF internal isolation – the MTX series exploits the advantages of state of the art technological solutions to achieve high reliability and comprehensive system flexibility – all at reduced size.

The transmitter is equipped with a direct digital synthesis modulator with the possibility to select any output frequency in the operating frequency range with 1Hz resolution. For digital modulations, it is possible to equip the Transmitter with the adaptive non-linear precorrection module to automatically improve the MER. Also adaptive linear precorrection is available for specific configurations.

The GNSS receiver option, specifically developed for the timing function, provides time and frequency signals (1pps and 10MHz) necessary for the synchronization of the transmitter when operating in SFN Mode. This is a new concept Timing Reference GNSS Locked generator with unique special features, with proprietary algorithms, to prevent network de-synchronization and is also available in redundant configuration.

Maintenance as well as channel changing operations are simple and easy to perform. Careful product design brings high versatility, enhanced by the provision of specific options and giving compliance with major world digital and analog terrestrial TV broadcasting standards.

Power amplifiers are available both in AB class or Doherty broadband configurations featuring very high efficiency.
