DT-722: 4 input DVB-T combiner with one single amplified output

Combiner with 4 inputs and an amplified output, 130 dBµV (+22 dBm) aprox.

The DT-722 is a combiner with 4 inputs and an output designed to mix output RF signals of COFDM modulators and transmodulators with DTT channels available in the area.

The system provides an amplified output of 130 dBµV (+22 dBm) frequently required in SMATV systems.

This is a solution of higher quality than those that often use Z connections, given that preserves better the original quality and maintains lower noise levels.

FREQUENCY MARGIN From 50 MHz (C-2) to 860 MHz (C-69)
INPUTS 4 inputs Female BNC, 75 Ω impedance
RF OUTPUT 1 female BNC output, 75 Ω impedance
Maximum output level
  • 1 channel at 130 dBµV
  • 2 channels at 127 dBµV
  • 4 channels at 124 dBµV
  • 8 channels at 121 dBµV
  • 16 channels at 118 dBµV
CONFIGURATION AND POWER SUPPLY Through the DT-800 control and power supply unit. Control can be done remotely from to PC.
