Digital TV Transmitters, Gap Fillers and Transposers for SFN/MFN networks.

  

DB Elettronica Digital TV Transmitters are designed to be compatible with all the International standards (DVB-T. DVB-H, ATSC, ISDB…).

All Digital TV Transmitters models, having output power between 2 Wrms and 12 Wrms, are equipped with high quality digital modulators with superior precision digital precorrectors.

The latest HI-ADC technology is a standard feature of IV and V band digital transmitters for the ultra-linear amplification of digital signals.


This technology is obtained throughout an innovative use of the latest generation “laterally diffused metal oxide” technology which, maintaining the same consumption levels, the same video parameters and the same dimensions, doubles the output power if compared to the past technology.

 

The new Gap Filler and Transposers line for SFN (for iso-frequency signal transmissions) and MFN networks, is composed of the latest generation products characterized by high-quality features that include non-linearity and echo-canceller precorrections functions for Gap Fillers.
 

Gap Filler:

  • Linear and non-linear precorrection
  • Adaptative echo-canceller
  • Sincronization to na external GPS reference  (SFN)
  • Remote control interface
  • Easy frequency change (1Hz steps)

Transposer:

  • Repetition of the signal with low phase oscillators to optimize the modulation
  • Linear and non-linear precorrection (even adaptative under request)
  • Remote control interface
  • Easy frequency change (1Hz steps)
