IF/Channel TV converter

Itel Broadcast

  • General. The TIX converter translates the standard IF signal frequency to the TV III, IV/V band desired channel. The RF power output is 1 W for the version TIX 1 , 2 W for version TIX 2, and 5 W for TIX 5.
  • Synthetized. The local oscillator frequency is producted by Voltage Controlled Oscillator (VCO) and stabilized by PLL, which allows easy selection of the desire output channel. The PLL reference frequency is a temperature compensated quartz oscillator.
  • High stability of RF output signal level. Precision AGC circuits enables it have a small variation of the RF output signal.
  • Broadband. The output amplifiers are broaband and in the case of changing output channel, additional tuning is not necessary.
  • Modular construction. For easy maintenance all circuits are built up in sin cassettes which can be exchanged and interconnected without retuning. The active modules are broadband, the passive modules provide for selection.
  • Controls and switches to operate on converter are arranged, in clear manner on the front pannel .
  • Solar cells power supply. The set can be supplied by AC power mains and a solar cells/battery at the same time by means of a low consuption regultor circuit that automatically switches on.
