WB1100KLII outdoor trunk bi-directional amplifier is mainly used for bi-directional trunk transmission of CATV television image signal, digital TV signal, telephone voice signals and data (or compressed data) signal. Advanced and mature circuits, scientific and reasonable process structures and high quality materials, ensure the excellent performance. It is the first choice product to build the large or middle-sized CATV bi-directional transmission network.
* Low noise MMIC + GaAs power double output.
* Plug-in equalizer and attenuator.
* Two-way tap or splitter output.
* 5 ~1003MHz, Frequency division optional.
* Downstream Gain≥ 38 dB.
* Upstream Gain≥ 24 dB.
* Power Consumption≤ 20W .
* Operating Temperature: -20℃ ~ +55℃ .
* Operating Voltage: AC220V or AC60V (50Hz).
* Dimension: 270mm(L)X 215mm(W)X 118mm(H).
