MB1000 Mini bridger amplifier (GaN hybrid, gain: 38, 42, 44 dB, DF modules and return path hybrid)

The MB1000 Mini bridger amplifier (GaN hybrid, gain: 38, 42, 44 dB, DF modules and return path hybrid) (Part number: MB10XXD-XX-XX) from Comtech is a HFC Amplifiers. Hybrid fiber-coaxial (HFC) Amplifier is a device used to amplify signals flowing in both directions, also it used at intervals to overcome cable attenuation and passive losses of the electrical signals caused by splitting or tapping the coaxial cable.

The MB1000 bridger amplifier works with 2 independent output stages, the second one of them can be divided symmetrically or asymmetrically by a passive module. They have a common gain and slope control option, while the 2 independently fed lines have 2 independently managed automatic ingress switches. The device is available with 3 different gain values. Based on this and on the modular style the amplifier can act as a key part of a larger network.
