CHT - 9750DFWP,CHT - 9750DF-PD(CATV Amplifier)

These devices are bidirectional amplifiers of indoor CATV. By amplifying loss of residential coaxial lines and passive elements, optimal input on TV sets and terminals of subscribers is maintained. By amplifying signals which are sending conditions of terminals and other information backward, they are devices to transmit them to headend centers.

Product Features

• This was designed so that frequency characteristics of 5.75~41.75MHz reverse and 54~864MHz forward are excellent. The level

    deviation was minimized between channels.
• By selecting exclusive Hybrid IC per band, large output and multi-channel transmission are possible. Especially, safety of reverse

    signals is greatly excellent.
• Because the sides are all-in-one heatproof plates, heatproof effect is excellent.
• The case is aluminum and so strong. Also, it is coated with film and printed, the appearance is pretty.
• Transmission frequency bands were reverse owing to the change of inside diplex filters. Change possibility into bands of 5.75~65㎒

    reverse and 88~864㎒ forward
• By selecting guaranteed SMPS, since low exothermic condition of 11W power consumption is maintained, causes of life decrease

    and breakdown occurrence due to high heating can be removed.

• Since 5/8-24 pin type connectors are directly linked, access to 7C, 10C, and 12C cables can be possible.

• By selecting Hybrid IC of large output (second stage forward and first stage reverse), it was designed to output maximum 115㏈㎶

    forward.
• Designed into Plug In (way of PAD) of gain control and slope control
• From designing input and output connectors into F and FT forms, convenience of users were contributed.
• In the future, due to frequency changes reverse and forward, the way of Plug In was chosen in order to be able to change band

    separators.
• Design to drastically change from AC43 to 90V (input option specifications)
• With side all-in-one exothermic plates, exothermic effect is excellent. When signal levels are amended on spots, the doors can be

    opened and closed briefly.
