WA1200 outdoor bidirectional AGC trunk amplifier is a new high gain amplifier. Adopt mature and optimized circuit design, scientific and rational internal process, high quality materials, and built-in high performance AGC control circuit, to ensure the stable gain and low distortion. It's the first choice equipment for large and medium-sized CATV bidirectional transmission network.
* RF AGC control for forward path.
* Plug-in equalizer and attenuator.
* GaAs power double output.
* Two-way splitter or tap output.
* 5 ~1003MHz, Frequency division optional.
* Downstream Gain≥ 38 dB.
* RF AGC range: ±4dB（ input） /±0.5dB（ output） .
* Upstream Gain≥ 22 dB.
* Power Consumption≤ 22W.
* Operating Temperature: -20℃ ~ +55℃ .
* Operating Voltage: AC220V or AC60V（ 50Hz）.
* Dimension: 260mm(L)X 200mm(W)X 130mm(H).
