The TD-522 is a combiner to be assembled in a rack cabinet of 19 inches and 1U height. It is an instrument designed to combine different RF (COFDM) signals in DVB-T format. The system provides 46 dBm amplification and an output power of 130 dBµV (+22 dBm) which allows offair distribution in reduced areas.

The TD-522 can combine up to 4 RF input signals from different sources, such as DTT signals, CCTVs, modulators and more, distributing the combined RF output signal through the distribution network.

This is a solution of higher quality than those often used by Z connections, due to it preserves the original quality better and maintains lower noise levels.

FREQUENCY RANGE	From 50 MHz to 860 MHz
MODULATION	COFDM
RF OUTPUT COFDM POWER GAIN MAX. OUTPUT LEVEL	22 dBm 46 dB ±3 dB between each input - output 1 channel to 130 dBµV, 2 channels to 127 dBµV, 4 channels to 124 dBµV and 8 channels to 121 dBµV
RF INPUT MAX. COFDM INPUT LEVEL	4 inputs 1 channel to 84 dBµV ± 3dB, 2 channels to 81 dBµV ± 3 dB, 4 channels to 78 dBµV ± 3 dBµV and 8 channels to 75 dBµV ± 3 dB
