WA1300 series outdoor Bi-directional Trunk Amplifier is the new developed high-gain amplifier. Mature and optimized circuit design, scientific and reasonable internal process and high quality materials, ensure the stable gain and low distortion. It is the best choice for building large or middle-sized CATV bi-directional transmission network.
* Plug-in equalizer and attenuator.
* Two ways GaAs power double output.
* 5 ~1003MHz, Frequency division optional.
* Downstream Gain≥ 40 dB.
* Upstream Gain≥ 20 dB.
* Power Consumption≤ 30W.
* Operating Temperature: -20℃ ~ +55℃ .
* Operating Voltage: AC220V or AC 60V (50Hz).
* Dimension: 320mm(L)X 200mm(W)X 140mm(H).
