Introduction: The WF-1232KL Building Amplifier is a high gain, low power, indoor bidirectional building amplifier that can be used in a 1.2 GHz cable television two-way cable transmission network. Features: Operating frequency: 5 ~ 85/110 ~ 1218MHz; can support DOCSIS 3.1 system. The downlink channel supports the RF AGC control function; the external RF detection port. Aluminum die-cast housing, the thickness of the whole machine is only 55mm, and the power consumption is only 5W. Technical Parameters Operating frequency: 5 ~ 85/110 ~ 1218 MHz Downstream channel maximum gain: ≥ 32 dB Downstream channel carrier composite triple beat ratio: ≥ 60 dB Downlink channel carrier composite quadratic beat ratio: ≥ 60 dB Upstream channel maximum gain: ≥ 17 dB Machine power consumption: ≤ 5W Working temperature: -20 ~ +55 °C Working voltage: AC 90 ~ 240V Dimensions: 200mm (L) X 115mm (W) X 55mm (H)
