Multiple amplifiers systems – Television Transmitters and Transposers


TX Series is EuroCaster´s High Power transmitter range, available in different versions with different output powers from 1500 to 20000 W rms (from 5000 to 24000 W p.s. when operating in analogue standards).

Equipment of the TX series are composed of some main subparts:

  • An exciter (dual driver as an option), with native adaptive pre-correction circuits, bringing multiple input interfaces (ASI, AET, EDI, IP, Satellite) and on-board GPS / GLONASS receiver for accurate synchronization in SFN environments;
  • Several amplifier stages (from 2 to 8 depending on the model and the output power level);
  • A control and monitoring unit, with embedded change over system 
  • An innovative and highly efficient Liquid cooling system.


TX  transmitters support several digital modulation standards (DVB-T/H/T2, ISDB-T/Tb, DAB/DAB+/T-DMB, ATSC), as well as dual-cast analog operation (supporting PAL and NTSC). TX obviously incorporates the innovative and distinctive engineering that has made the success of the low/medium power range of EuroCasters transmitters, allowing unparalleled ease of use and maintenance.


Main features:

  • Compact dimensions (single 19” Rack, including output filter)
  • Output Power up to 2700W rms (COFDM), up to 3750W rms (ATSC) or up to 6800W p.s. (analogue)
  • High efficiency broadband or wideband amplifier technology both in UHF and VHF bands
  • Single or Dual driver
  • Enhanced redundancy in Power Supply Units
  • DVB-T/H/T2, ISDB-T/Tb, DAB/DAB+/T-DMB, ATSC, PAL, NTSC, NICAM modulations fully supported
  • Embedded Re-Multiplexer/Layer Combiner/TS to BTS (188 to 204 byte) converter for ISDB-Tb
  • Adaptive pre-correction circuits
  • On-board high stability GPS / GLONASS receiver with battery
  • Flexible input interfaces (ASI/BTS/SMPTE-310M, ETI, EDI, IP, Satellite, analog audio and video)
  • control and monitoring unit with embedded change over and switching system
