WF1100KLE-I outdoor trunk bidirectional amplifier is mainly used for bidirectional 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 equipment to build large or middle-sized CATV bidirectional transmission network.
* Low noise MMIC + GaAs power double output.
* Plug-in equalizer and attenuator.
* Two-way tap or splitter output, cast aluminum waterproof housing.
* 5 ~1003MHz, Frequency division optional.
* Downstream Gain≥ 38 dB.
* Upstream Gain≥ 24 dB.
* Power Consumption ≤ 20W.
* Operating Temperature: -20℃ ~ +55℃ .
* Operating Voltage: AC 220V or AC 60V (50Hz).
* Dimension: 220mm (L) X 205mm (W) X 65mm (H).
