1.2GHz CATV bi-directional amplifier

INQUIRY

Mode: MIC-1220DRA

Overview:

MIC-1220DRA CATV bi-directional amplifier is a kind of high-performance two-way amplifier, operation bandwidth to 1.2G, supporting DOCSIS 3.1 system. It adopts GaAs amplification module, to improve the machine’s performance index greatly. Pluggable frequency division module, can provide multiple frequency division type. The unified equalization and attenuation inserts are convenient to user debugging and operating. With good upstream and downstream channels’ isolation, it applies to large HFC network, to ensure the stability of system in the whole network.

Features

● 1.2G bandwidth, supporting DOCSIS 3.1

● Good distortion index

● Good heat dissipating and waterproof function

● -20～＋55℃ wide range of operation temperature

● 6KV port surge protection

● 10A port over-current capacity

● The unified type equalization and attenuation insert

● Pluggable output distribution
